Android ConstraintLayout - moving View fails

My goal is to dynamically create a grid of TextViews in a ConstraintLayout. I've seen many examples but there's an issue that I'm just not seeing. I've broken the task into two steps:
creating the View
positioning the View
I seem to have mastered the first but not the second. Usually I can modify a View's ConstraintSet if it is defined in XML and positioned at startup, but never when I've created it programmatically. When I create a View I'm careful to set an id, layout_width and layout_height. Method's I've tried for creating a new View:
creating it and setting parameters from a new LayoutParameters object
creating it and setting parameters from another View.
inflating it from an XML template.

import java.util.Locale;
public class MainActivity extends AppCompatActivity {

final int START = ConstraintSet.START;

final int TOP = ConstraintSet.TOP;
int counter = 0;
View anchorView;

#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}
public void makeView(View view) {
nextView = new TextView(this);
nextView.setLayoutParams(anchorView.getLayoutParams());
int nextViewId = nextView.generateViewId();
nextView.setId(nextViewId);
int ViewCount = ++counter;
String newName = String.format(Locale.US, "View %02d", ViewCount);
nextView.setText(newName);
this.mainLayout.addView(nextView);
}
public void placeView(View view) {

set.clone(this.mainLayout);
set.clear(nextView.getId());

set.connect(nextView.getId(), START, anchorView.getId(), END);
set.applyTo(this.mainLayout);
anchorView = nextView;
}
}

Solved.
clear(nextView.getId()); was too aggressive. I replaced that line with more specific directives:
clear(nextView.getId(), END);
clear(nextView.getId(), BOTTOM);
It's now working as intended, with a little revision my app creates a horizontal chain as I Add and Place:
[View 00][View 01][View 02]

android layout is not showing proper on some resolutions

My android layout with grid view is not showing properly on 480 x 854 pixels (~196 ppi pixel density) device.and please suggest me is there any method to work with layout creation at run time.

Android categorizes device screens using two general properties: size
and density. You should expect that your app will be installed on
devices with screens that range in both size and density.
Create Different Layouts
To optimize your user experience on different screen sizes, you should create a unique layout XML file for each screen size you want to support. Each layout should be saved into the appropriate resources directory .
More info you can visit official guideline
Supporting Different Screen Sizes

#N.shah , For Gridview, You should make all view dynamic, So that all the cells come exactly on each and every device
How We can do this
Like we have 4 rows and 2 columns
All 4 rows should show on window
1. Find out the device width and height
2. Lets say height is X. Find out height of status bar i.e Y and action bar Z
3. Find out the exact height where we have to show our gridview i.e
X=X-(Y+Z)
4. Divide the X by no. of rows you want to show to find out row height i.e R
R=X/4( where 4 is no. of rows)
5. Create an xml which you want to show in gridview

ListView rows with rounded corners

I am currently working on rewriting one of my iOS apps to release on Android. I'm making good progress but I am looking for some guidance regarding the best way to approach the list rows.
These are the cells/rows I am trying to recreate:
As you can see, I have a white background view with padding around each edge and rounded corners, so I guess for this I would need to embed everything within a view of some sort? The other part I am unsure about is how to create the coloured circle on the right. Would this be another view with rounded corners and a coloured background? I haven't managed to figure out how to get this to the right of the two textViews that I currently have. So if anyone could give a code example then that would be great.
This is my current XML:
<ImageView
android:layout_width="78dp"
android:layout_height="78dp"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:scaleType="centerCrop"
android:adjustViewBounds="false"
android:id="#+id/attractionImageView"
android:contentDescription="Attraction Image"
android:background="#color/colorPrimary" />
<ImageView
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginLeft="5dp"
android:layout_marginTop="5dp"
android:background="#drawable/fast_pass"
android:id="#+id/fastPassImageView" />
<LinearLayout android:orientation="vertical" android:layout_height="match_parent" android:layout_width="fill_parent" android:layout_toEndOf="#+id/attractionImageView" android:layout_toRightOf="#+id/attractionImageView">
<TextView
android:layout_width="match_parent"
android:layout_height="49dp"
android:id="#+id/attractionNameTextView"
android:text="Attraction Name"
android:layout_marginLeft="5dp"/>
<LinearLayout android:orientation="horizontal" android:layout_height="match_parent" android:layout_width="fill_parent" android:layout_toEndOf="#+id/attractionImageView" android:layout_toRightOf="#+id/attractionImageView">
<ImageView
android:layout_width="13dp"
android:layout_height="13dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:id="#+id/updatedImageView"
android:background="#drawable/updated"
android:layout_gravity="center_vertical"/>
<TextView
android:layout_width="match_parent"
android:layout_height="29dp"
android:id="#+id/updatedTextView"
android:text="Updated"
android:gravity="center_vertical"/>
</LinearLayout>
</LinearLayout>
This seems to work well for everything I've got so far, but I'm not sure where to go from here. This is how it looks:
Any suggestions?

For the colored circle- I'd suggest just a text view set to the proper size with a circle drawable set as the background of the view. Should get what you want.
For the background- I'd just stick the entire row in either a linear or relative layout, then set a RoundedBitmapDrawable as the background of the layout. That will give you the rounded background effect. If necessary add some margin to the top and bottom of each view to increase the gap between items.

I suppose that you're using custom views for your listview's items, if so, I would set the background of the custom view to something like this:
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#color/white" />
<stroke android:width="4dp" android:color="#color/beige" /> //If you want a stroke
<corners
android:topLeftRadius="20dp"
android:topRightRadius="20dp"
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />

As an alternate solution, I just got something working with CardViews and using Picasso with a CircleTransformation for the circle.
In this simple example, I used a RecyclerView of CardViews.
First, here is the CircleTransformation class that is used by Picasso:
import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Paint.Style;
import com.squareup.picasso.Transformation;
public class CircleTransform implements Transformation {
#Override
public Bitmap transform(Bitmap source) {
int size = Math.min(source.getWidth(), source.getHeight());
int x = (source.getWidth() - size) / 2;
int y = (source.getHeight() - size) / 2;
Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
if (squaredBitmap != source) {
source.recycle();
}
Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());
Canvas canvas = new Canvas(bitmap);
BitmapShader shader = new BitmapShader(squaredBitmap, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG | Paint.DITHER_FLAG | Paint.FILTER_BITMAP_FLAG);
paint.setShader(shader);
float r = size/2f;
canvas.drawCircle(r, r, r-1, paint);
Paint paintBorder = new Paint();
paintBorder.setStyle(Style.STROKE);
paintBorder.setColor(Color.argb(84,0,0,0));
paintBorder.setAntiAlias(true);
paintBorder.setStrokeWidth(1);
canvas.drawCircle(r, r, r-1, paintBorder);
squaredBitmap.recycle();
return bitmap;
}
#Override
public String key() {
return "circle";
}
}
Here is the Fragment:
public class BlankFragment extends Fragment {
public BlankFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_blank, container, false);
RecyclerView rv = (RecyclerView) rootView.findViewById(R.id.rv_recycler_view);
rv.setHasFixedSize(true);
MyAdapter adapter = new MyAdapter(new String[]{"testone", "testtwo", "testthree", "testfour"}, getActivity());
rv.setAdapter(adapter);
LinearLayoutManager llm = new LinearLayoutManager(getActivity());
rv.setLayoutManager(llm);
return rootView;
}
}
fragment_blank.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/rv_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
The adapter, which includes the defaultCircleWithText() method for drawing the circle and text. Here I'm just using one color for the circles, but you can extend this to set the correct circle color for each row:
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Paint.Style;

private String[] mDataset;
Context mContext;
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public static class MyViewHolder extends RecyclerView.ViewHolder {
public CardView mCardView;
public TextView mTextView;

public MyViewHolder(View v) {
super(v);
mCardView = (CardView) v.findViewById(R.id.card_view);
mTextView = (TextView) v.findViewById(R.id.tv_text);
mImageView = (ImageView) v.findViewById(R.id.iv_image);
}
}
// Provide a suitable constructor (depends on the kind of dataset)
public MyAdapter(String[] myDataset, Context context) {
mDataset = myDataset;
mContext = context;
}
// Create new views (invoked by the layout manager)
#Override
public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
View v = LayoutInflater.from(parent.getContext())

// set the view's size, margins, paddings and layout parameters
MyViewHolder vh = new MyViewHolder(v);
return vh;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
holder.mTextView.setText(mDataset[position]);
Drawable drawable = new BitmapDrawable(mContext.getResources(), defaultCircleWithText("test"));
Picasso.with(mContext).load((String)null).fit().transform(new CircleTransform()).placeholder(drawable).into(holder.mImageView);
}
#Override
public int getItemCount() {
return mDataset.length;
}
public final static int BIG_IMAGE = 138;
public static Bitmap defaultCircleWithText(String text) {
int size = BIG_IMAGE;

Paint p_text = new Paint();
p_text.setAntiAlias(true);
p_text.setColor(Color.WHITE);
p_text.setTextSize(58);
RectF bounds = new RectF(0, 0, c.getWidth(), c.getHeight());
// measure text width
bounds.right = p_text.measureText(text, 0, text.length());
// measure text height
bounds.bottom = p_text.descent() - p_text.ascent();
bounds.left += (c.getWidth() - bounds.right) / 2.0f;
bounds.top += (c.getHeight() - bounds.bottom) / 2.0f;

Result:

ScrollView Layout does not fill the whole screen

I got an Activity with two Fragments (one list one normal).
And the normal Fragment inflates a Scrollview containing a LineaLayout (vertical) and this layout contains TextViews.
The ScrollView and layout_width and layout_height are match_parent, so I think the whole screen should be used. But on the bottom there is still a "gap".
I hope you can help me.

Thanks a lot.
Edit: Even the proble is already fixed with: android:fillViewPort="true", I want to show you the problem.
But I don't have enough reputation to post a picture.
Sorry!

If i'm not mistaken, the ViewGroup's height (LinearLayout's height in your case), that is the (only) child inside a ScrollView, is always interpreted as wrap_content, since that content can be larger than the ScrollView's height (hence the scrollbars).
This also means that if the content is smaller, the ScrollView's content (child) may not necessarily stretch to fill the screen.
In order to visually help you fix this, we need to see a screenshot of your problem.
Maybe setting android:fillViewport="true" on the ScrollView will fix your issue:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
android:fadeScrollbars="false"
android:scrollbars="vertical" >
In your ScrollView add an attribute ie.
android:fillViewport="true"

inflater.inflate(R.layout.menu_content_main, container);
should be
inflater.inflate(R.layout.menu_content_main, container, false);

Replace ScrollView with NestedScrollView it will also solve the problem of nested scrolling.
<androidx.core.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent">
</androidx.core.widget.NestedScrollView>

I had a similar problem and could only fix it with a Helper Class. I found the original code online and this is my implementation of it.

How did Google manage to do this? Slide ActionBar in Android application

I really want to implement this (the side navigation) in an app of my own, does anyone know how Google managed to do this?
They seem to have pulled the current window aside and put in a fly-in navigation of their own.

In fact, there's a way to do this. Even without implementing your own ActionBar.
Just have a look at the hierachyviewer! (Located in the tools directory)
There's the DecorView, and a LinearLayout as a child. This LinearLayout contains both the ActionBar and the other content. So, you can simply apply some FrameLayout.LayoutParams to this LinearLayout and get some space on the left side this way. Then, you can fill this space with your menu-ListView and overlay the other content with a FrameLayout, that, when it's clicked, collapses the menu. So, here's some code:
First, the class for collapsing / expanding (SlideMenu.java):
package your.cool.app;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.graphics.Rect;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.view.Window;
import android.view.animation.TranslateAnimation;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.FrameLayout;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;
public class SlideMenu {
//just a simple adapter
public static class SlideMenuAdapter extends ArrayAdapter<SlideMenu.SlideMenuAdapter.MenuDesc> {
Activity act;
SlideMenu.SlideMenuAdapter.MenuDesc[] items;
class MenuItem {
public TextView label;
public ImageView icon;
}
static class MenuDesc {
public int icon;
public String label;
}
public SlideMenuAdapter(Activity act, SlideMenu.SlideMenuAdapter.MenuDesc[] items) {
super(act, R.id.menu_label, items);
this.act = act;
this.items = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
if (rowView == null) {
LayoutInflater inflater = act.getLayoutInflater();
rowView = inflater.inflate(R.layout.menu_listitem, null);
MenuItem viewHolder = new MenuItem();
viewHolder.label = (TextView) rowView.findViewById(R.id.menu_label);
viewHolder.icon = (ImageView) rowView.findViewById(R.id.menu_icon);
rowView.setTag(viewHolder);
}
MenuItem holder = (MenuItem) rowView.getTag();
String s = items[position].label;
holder.label.setText(s);
holder.icon.setImageResource(items[position].icon);
return rowView;
}
}
private static boolean menuShown = false;
private static View menu;
private static LinearLayout content;
private static FrameLayout parent;
private static int menuSize;
private static int statusHeight = 0;
private Activity act;
SlideMenu(Activity act) {
this.act = act;
}
//call this in your onCreate() for screen rotation
public void checkEnabled() {
if(menuShown)
this.show(false);
}
public void show() {
//get the height of the status bar
if(statusHeight == 0) {
Rect rectgle = new Rect();
Window window = act.getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rectgle);
statusHeight = rectgle.top;
}
this.show(true);
}
public void show(boolean animate) {
menuSize = Functions.dpToPx(250, act);
content = ((LinearLayout) act.findViewById(android.R.id.content).getParent());
FrameLayout.LayoutParams parm = (FrameLayout.LayoutParams) content.getLayoutParams();
parm.setMargins(menuSize, 0, -menuSize, 0);
content.setLayoutParams(parm);
//animation for smooth slide-out
TranslateAnimation ta = new TranslateAnimation(-menuSize, 0, 0, 0);
ta.setDuration(500);
if(animate)
content.startAnimation(ta);
parent = (FrameLayout) content.getParent();
LayoutInflater inflater = (LayoutInflater) act.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
menu = inflater.inflate(R.layout.menu, null);
FrameLayout.LayoutParams lays = new FrameLayout.LayoutParams(-1, -1, 3);
lays.setMargins(0,statusHeight, 0, 0);
menu.setLayoutParams(lays);
parent.addView(menu);
ListView list = (ListView) act.findViewById(R.id.menu_listview);
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//handle your menu-click
}
});
if(animate)
menu.startAnimation(ta);
menu.findViewById(R.id.overlay).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
SlideMenu.this.hide();
}
});
Functions.enableDisableViewGroup((LinearLayout) parent.findViewById(android.R.id.content).getParent(), false);
((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(false);
((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(false);
menuShown = true;
this.fill();
}
public void fill() {
ListView list = (ListView) act.findViewById(R.id.menu_listview);
SlideMenuAdapter.MenuDesc[] items = new SlideMenuAdapter.MenuDesc[5];
//fill the menu-items here
SlideMenuAdapter adap = new SlideMenuAdapter(act, items);
list.setAdapter(adap);
}
public void hide() {
TranslateAnimation ta = new TranslateAnimation(0, -menuSize, 0, 0);
ta.setDuration(500);
menu.startAnimation(ta);
parent.removeView(menu);
TranslateAnimation tra = new TranslateAnimation(menuSize, 0, 0, 0);
tra.setDuration(500);
content.startAnimation(tra);
FrameLayout.LayoutParams parm = (FrameLayout.LayoutParams) content.getLayoutParams();
parm.setMargins(0, 0, 0, 0);
content.setLayoutParams(parm);
Functions.enableDisableViewGroup((LinearLayout) parent.findViewById(android.R.id.content).getParent(), true);
((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(true);
((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(true);
menuShown = false;
}
}
Some helping methods (for me, in static Functions.java):
public static int dpToPx(int dp, Context ctx) {
Resources r = ctx.getResources();
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, r.getDisplayMetrics());
}
//originally: http://stackoverflow.com/questions/5418510/disable-the-touch-events-for-all-the-views
//modified for the needs here
public static void enableDisableViewGroup(ViewGroup viewGroup, boolean enabled) {
int childCount = viewGroup.getChildCount();
for (int i = 0; i < childCount; i++) {
View view = viewGroup.getChildAt(i);
if(view.isFocusable())
view.setEnabled(enabled);
if (view instanceof ViewGroup) {
enableDisableViewGroup((ViewGroup) view, enabled);
} else if (view instanceof ListView) {
if(view.isFocusable())
view.setEnabled(enabled);
ListView listView = (ListView) view;
int listChildCount = listView.getChildCount();
for (int j = 0; j < listChildCount; j++) {
if(view.isFocusable())
listView.getChildAt(j).setEnabled(false);
}
}
}
}
Then, the layouts:
Layout of the menu (res/layout/menu.xml)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="250dip"
android:background="#color/darkblack">
<ListView
android:id="#+id/menu_listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#color/dividerblack"
android:dividerHeight="2dip" />
</LinearLayout>
<FrameLayout
android:id="#+id/overlay"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</LinearLayout>
Layout of the listitems (res/layout/menu_listitem.xml):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent" >
<ImageView
android:id="#+id/menu_icon"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginRight="5dip"
android:layout_marginLeft="10dip"
android:layout_marginTop="10dip"
android:layout_marginBottom="10dip" />
<TextView
android:id="#+id/menu_label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#color/white"
android:textSize="24dp"
android:layout_marginTop="10dip"
android:layout_marginBottom="10dip" />
</LinearLayout>
How to use it:
In your onCreate():
private SlideMenu slidemenu;
#Override
public void onCreate(Bundle savedInstanceState) {
//your onCreate code
slidemenu = new SlideMenu(this);
slidemenu.checkEnabled();
}
In the handler for your ActionBar homebutton:
slidemenu.show();
That's it!
And now, a little screenshot of it in action:
As far as I know, it is working. If you experience any problems or my explanations are not clear, please contact me!
EDIT: ExtendedViewPager & ExtendedPagerStrip:
ExtendedViewPager:
package your.cool.app;
//source: http://blog.svpino.com/2011/08/disabling-pagingswiping-on-android.html
import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;
public class ExtendedViewPager extends ViewPager {
private boolean enabled;
public ExtendedViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
this.enabled = true;
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onTouchEvent(event);
}
return false;
}
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onInterceptTouchEvent(event);
}
return false;
}
public void setPagingEnabled(boolean enabled) {
this.enabled = enabled;
}
}
ExtendedPagerTabStrip:
package your.cool.app;
//source: http://blog.svpino.com/2011/08/disabling-pagingswiping-on-android.html
import android.content.Context;
import android.support.v4.view.PagerTabStrip;

}
}
I use this SlideMenu for an Activity with a ViewPager with PagerTabStrip for tabs like Talk, Market etc. You can't disable these Views in an easy way, so the two classes above just extend them to stop the onTouch event when disabled.

There are several attempts at doing this, however I have yet to find a lib or source code on how to implement it successfully with actionbar accross all api levels. One promising lib is here
https://github.com/jfeinstein10/SlidingMenu
here is a video of the example app.
here is the Google Play app link.
This does work with ActionbarSherlock. You will have to build the SlidingMenu library with ABS to get it working. Works and looks great!

Did a roundup of the original implementation and added XML parsing as well as autodetection of a possibly present actionbar, so it works with the native as well as a support action bar such as ActionBarSherlock.
The whole thing is now a library project together with an example app and is described over at Sliding Menu for android Thanks to scirocco for the initial idea and code!

If you are using API level greater that 11 you can use a much simpler approach inspired by the answer given by #Scirocco
// get content parent that is basically the whole
// app screen (viewed from hierarchy viewer)
final LinearLayout content =
(LinearLayout) findViewById(android.R.id.content).getParent();
// make new value animator with range from 0 to 1
final ValueAnimator animator = ValueAnimator.ofFloat(0, 1);
// set custom duration
animator.setDuration(500);
// on update is called for every value in the
// given range in time frame defined by the duration
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
// get the current value
float value = ((Float) (animation.getAnimatedValue())).floatValue();
// translate by that value, minus means translate left
content.setTranslationX(-250 * value);
}
});
// start the animator
animator.start();
// make or inflate custom view for test purposes
Button textView = new Button(this);
textView.setText("TestButton");
// add it to the frame layout that is the parent of the content on position 0
FrameLayout parent = (FrameLayout) content.getParent();
parent.addView(textView, 0);
The idea here is to use ValueAnimator that transforms and not just animates the main layout with the Action bar, so you can interact with the inflated view you want to use as a sliding panel.
You should replace the hardcoded values with something that is of use to your app.
I hope this helps :)

Well currently im working on a project and came across Sliding menu,i googled but gets very disappointed to see that no one has given some piece of code or some hint for how to start making a sliding menu,but every one has given link to some github's projects/libraries to use,I decided to do it myself and finally i have my own Sliding Menu Ready...
I have Spent two days on it
1. on making animations of sliding
2. on making it work with all screen resolutions
Its really easy and simple once you get some idea about Animations, i have read some where,its not sensible to re-invent the Wheel(people who are refering to github source code of sliding menu),but i beleif that you should atleast once try to make your own so you get a idea how it actually works and functions :P
so this is a picture of how my sliding menu will going to work

There you go a complete working and functional Sliding Menu, and you can customized it to meet your requirements,if any one still have some problems setting up,feel free to ask,i feel pleasure to help you out :)

I've created my own solution for sliding away the view and revealing a menu underneath, as many other solutions appeared to not work on older Android versions or lacked proper instructions on how to get it to work.
My solution has the following features:
Provides support for sliding away a view to reveal a menu that lies underneath it
Both the menu and the view above can be any custom View
Supported on old Android versions (tested to work at least on Android 2.2)
Works with PhoneGap / Cordova projects
The solution uses a custom layout, called SlidingMenuLayout, that you are expected to add 2 views to. The first view you add is the menu, the second is the main view.
The simplest way to add the layout to your existing project is to override your Activity's setContentView() method:
#Override
public void setContentView(View view) {
SlidingMenuLayout layout = new SlidingMenuLayout(this);
layout.setLayoutParams(new LinearLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT,
0.0F));
layout.addView(new MenuView(this));
layout.addView(view);
super.setContentView(layout);
}
In this example, MenuView is the view that will actually show the menu. It is up to you to implement this view.
Finally, you can add a button (typically in the top left corner of your main view), that calls openMenu() or closeMenu() on the layout as appropriate.
The code for SlidingMenuLayout is found on the GitHub project page.

For those of you who uses the SlidingMenu library (https://github.com/jfeinstein10/SlidingMenu) there is a way to jack it in and it seems to work! With help of #Scirocco put this in your onCreate for the activity:
ViewGroup decorView = (ViewGroup) getWindow().getDecorView();
mSlidingMenu = new SlidingMenu(this);
ViewGroup mainContent = (ViewGroup) decorView.getChildAt(0);
decorView.removeView(mainContent);
mSlidingMenu.setContent(mainContent);
decorView.addView(mSlidingMenu);
mMenu = (LinearLayout) View.inflate(this, R.layout.menuview, null);
mSlidingMenu.setMenu(mMenu);
mSlidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);
mSlidingMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
basically what it does is replacing the linearlayout in decor view with the slidingmenu instead.
Notice: Ive only tested it lightly but it seems to work.

public class ImprovedSlidingPaneLayout extends SlidingPaneLayout {
Context context;
FrameLayout left;
FrameLayout right;
Boolean canOpen = true;
public ImprovedSlidingPaneLayout(Context context) {
super(context);
this.context = context;
this.left = new FrameLayout(context);
this.right = new FrameLayout(context);
this.addView(left);
this.addView(right);
}
public ImprovedSlidingPaneLayout(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
}
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
if (canOpen)
return super.onInterceptTouchEvent(ev);
else
return false;
}
public ImprovedSlidingPaneLayout canOpen(Boolean canOpen) {
this.canOpen = canOpen;
return this;
}
public ImprovedSlidingPaneLayout makeActionBarSlide(Window window){
ViewGroup decorView = (ViewGroup) window.getDecorView();
ViewGroup mainContent = (ViewGroup) decorView.getChildAt(0);
decorView.removeView(mainContent);
setContentView(mainContent);
decorView.addView(this);
return this;
}
public ImprovedSlidingPaneLayout setMenuView(View view){
if((left.getChildCount()== 1)){
left.removeView(left.getChildAt(0));
}
left.addView(view);
return this;
}
public ImprovedSlidingPaneLayout setContentView(View view){
if((right.getChildCount()== 1)){
right.removeView(right.getChildAt(0));
}
right.addView(view);
return this;
}
public ImprovedSlidingPaneLayout setMenuWidth(int width){
left.setLayoutParams(new SlidingPaneLayout.LayoutParams(width, ViewGroup.LayoutParams.MATCH_PARENT));
return this;
}
}
this is my class extends SlidingPaneLayout. Can slide with actio
