I'm trying to populate a LinearLayout inside simple_pdf_example.xml with 10 printed_order_element2.xml just so I can generate a PDF with a ListView (which is actually a LinearLayout).
The problem is that when I do linearLayoutView.addView(v) 10 times, I don't see v inside the LinearLayout. I just see the original item I added in the xml just to see if the LinearLayout was rendering.
SimplePDFSaver.java:
package com.mypackage.example;

LayoutInflater inflater = getLayoutInflater();
View pdfLayout = inflater.inflate(R.layout.simple_pdf_example,
findViewById(android.R.id.content),
false);
int sizeSpec = View.MeasureSpec.makeMeasureSpec(2480, View.MeasureSpec.EXACTLY);
int sizeSpec2 = View.MeasureSpec.makeMeasureSpec(3508, View.MeasureSpec.EXACTLY);
pdfLayout.measure(sizeSpec, sizeSpec2);
int width = pdfLayout.getMeasuredWidth();
int height = pdfLayout.getMeasuredHeight();
pdfLayout.layout(0, 0, width, height);
LinearLayout linearLayoutView = pdfLayout.findViewById(R.id.linearLayoutView);
for (int i=0; i<10; i++) {
View v = getLayoutInflater().inflate(R.layout.printed_order_element2, null);
linearLayoutView.addView(v);
}
Runnable r = new Runnable() {
#Override
public void run() {
PdfDocument document = new PdfDocument();
PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(2480, 3508, 0).create();
PdfDocument.Page page = document.startPage(pageInfo);
pdfLayout.draw(page.getCanvas());
document.finishPage(page);
FileOutputStream outStream;
File file = new File(getExternalFilesDir(null), "file.pdf");
try {
outStream = new FileOutputStream(file);
document.writeTo(outStream);
document.close();
outStream.flush();
outStream.getFD().sync();
outStream.close();

This is what I get:
I believe the problem lies in this section of code:
public void generatePDF() {
LayoutInflater inflater = getLayoutInflater();
View pdfLayout = inflater.inflate(R.layout.simple_pdf_example,
findViewById(android.R.id.content),
false);
All of the rest of your code uses this inflated pdfLayout view:
LinearLayout linearLayoutView = pdfLayout.findViewById(R.id.linearLayoutView);
for (int i=0; i<10; i++) {
View v = getLayoutInflater().inflate(R.layout.printed_order_element2, null);
linearLayoutView.addView(v);
}
pdfLayout.draw(page.getCanvas());
The problem is that your pdfLayout view is never put on the screen. Your setContentView() call in onCreate() inflates a different layout, and the inflated pdfLayout is never attached to any view!
When you call inflate(int, View, boolean) and pass false as the third argument, you are telling the system to treat the second argument (the View) as the parent only in order to parse LayoutParams on the root of the inflated layout. The inflated layout is not added to the parent! You have to manually call parent.addView() with the inflated view.
How to fix it? It's hard to say, exactly, since I've got a few questions. But maybe just asking the questions will reveal the answer.
It's strange to see both a call to setContentView() and a call to inflate() that passes in android.R.id.content as the parent. Could you just call setContentView(R.layout.simple_pdf_example) in your onCreate(), and avoid the second inflate() call altogether?
If so, then you'd replace all calls to pdfLayout.findViewById() with direct findViewById() calls (since what was previously pdfLayout is now just your Activity's main content).
Your linearLayoutView lies in pdfLayout, but when you inflate pdfLayout you don't add it to the parent. Please, try this way:
View pdfLayout = inflater.inflate(R.layout.simple_pdf_example, findViewById(android.R.id.content));
Simply adding
pdfLayout.measure(sizeSpec, sizeSpec2);
pdfLayout.layout(0, 0, width, height);
after the for loop fixed everything. Thanks to Ben P. https://stackoverflow.com/users/8298909/ben-p
The problem is that the layout needs to me measured or layout() must be executed. I don't know for sure, but it has to do with it. I don't know if the 2 lines are needed but you can try to use only one and see what works
I would like to do something like this:
https://storage.googleapis.com/spec-host/mio-staging%2Fmio-design%2F1563837804615%2Fassets%2F1XlKhaQFU9aS84ACmF-EDjVKDgI4pPldv%2F02-overflowmenu.mp4
I would like to squeeze a "ViewGroup" as you can see in the video. In the meantime, I want to fade out the content in the ViewGroup at its original position. i.e. not pushing the content to the right.
Any idea how to implement this?
Thanks!
You can do such animations with Transition API. Declare two ViewGroups: first one is horizontal with cut/copy buttons, second is vertical with search/share buttons. Then switch these ViewGroups with TransitionManager. Then just provide Transition which describes how views on first and second ViewGroups appears and disappers.

showPopup1();
}
private void showPopup1() {
ViewGroup popup1 = (ViewGroup) getLayoutInflater().inflate(R.layout.popup_1, mSceneRoot, false);
popup1.findViewById(R.id.btnGo).setOnClickListener(v -> {
showPopup2();
});
Scene scene = new Scene(mSceneRoot, popup1);
TransitionManager.go(scene, getTransition(false));
}
private void showPopup2() {
ViewGroup popup2 = (ViewGroup) getLayoutInflater().inflate(R.layout.popup_2, mSceneRoot, false);
popup2.findViewById(R.id.btnBack).setOnClickListener(v -> {
showPopup1();
});
Scene scene = new Scene(mSceneRoot, popup2);
TransitionManager.go(scene, getTransition(true));
}

Last thing here is getTransition method. You can just use AutoTransition, it can handle easy layout changes.
private Transition getTransition(boolean open) {
return new AutoTransition();
}
Result:
Also just for demostration I wrote more complex transition where button on first viewgroup appear/dissapear with Slide animation.
private Transition getTransition(boolean open) {
Slide btnGo = new Slide(Gravity.RIGHT);
btnGo.addTarget("btn_go");
ChangeBounds bgBounds = new ChangeBounds();
bgBounds.addTarget("bg");
Fade btnBack = new Fade();
btnBack.addTarget("btn_back");
TransitionSet set = new TransitionSet();
set.setOrdering(TransitionSet.ORDERING_SEQUENTIAL);
if (open) {
set.addTransition(btnGo);
set.addTransition(bgBounds);
set.addTransition(btnBack);
} else {
set.addTransition(btnBack);
set.addTransition(bgBounds);
set.addTransition(btnGo);
}
return set;
}
Result:
Note that transitionName for background should be same in both layouts.
All transition classes here are from androix package so code is backward compatible. But if you need support pre Lollipop devices you should set transitionName via ViewCompat.setTransitionName method.
You can check my another answer with more difficult/custom transition.
i want to scroll my TextView at some portion of text that i know, and show it on top. this is my scrollView and TextView:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:scrollbars="vertical"
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp"/>
</ScrollView>
My text is an array of strings:
ScrollView scroll= (ScrollView) getActivity().findViewById(R.id.scroll);
TextView text = (TextView) getActivity().findViewById(R.id.text);
String book ="";
for(String line: lines){
book += line;
}
text.setText(book);
this is when i want to scroll:
String find = book[myindex];
int go = text.indexOf(find);
makeScroll(go);
this is my runnable:
private void makeScroll(final int go){
scrollRegole.post(new Runnable() {
public void run() {
scrollRegole.scrollTo(0, go);
}
});
}
this is not work, why? thanks!
Ok, the code is fine. It scrolls to the current (x,y) position of your "scrollView" as says:
http://developer.android.com/reference/android/widget/ScrollView.html#scrollTo(int, int)
So I think that is an interpretation trouble. Is not the same a "line" on the textView that a "y" coordinate on the ScrollView. So if you want to get the row number 15 for example, "go variable" cant be 15, it should be something proportional to the "TextSize" + padding + margin, etc...
Do you know what I mean?
Hope it helps.
EDIT:: Here is a test that I tried and it work fine if you know which is the row that you want. Maybe the trouble is that you didn't calculate the line properly
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ScrollView;
import android.widget.TextView;
public class MainActivity extends Activity {
ScrollView scroll;
TextView text;
EditText editText;
Button but;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text = (TextView) findViewById(R.id.text);
scroll = (ScrollView) findViewById(R.id.scroll);
but = (Button) findViewById(R.id.button1);
editText = (EditText) findViewById(R.id.editText1);
but.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
int go = Integer.valueOf(editText.getText().toString());
makeScroll(go);
}
});
}
private void makeScroll(final int go) {
scroll.post(new Runnable() {
public void run() {
scroll.scrollTo(0, go * text.getLineHeight());
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
and the xml

</ScrollView>
</LinearLayout>
EDIT:: EDIT:
In order to get the line, here is a possible solution:
Android TextView and getting line of text
As I said at the commentary, firstly get a vector that contains every line, then look for the word. And finally move to the current row with the previous code.
this is how i resolved my problem:
this is my new ScrollView:
<ScrollView
android:id="#+id/scroll"
android:layout_width="0dp"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:layout_weight="3" >
<LinearLayout
android:id="#+id/containerTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
here i add many TextView into my container:
if(scroll == null){
scroll = (ScrollView) getActivity().findViewById(R.id.scroll);
}
if(layout == null)
layout = (LinearLayout) getActivity().findViewById(R.id.containerTextView);
layout.removeAllViews();
for(String line: lines){
TextView text = new TextView(getActivity());
text.setText(line);
text.setTextSize(...));
layout.addView(text);
}
this is when i want to scroll:
private void calculateScroll(final LinearLayout layout, final int indexLine){
layout.addOnLayoutChangeListener(new OnLayoutChangeListener(){
#Override
public void onLayoutChange(View paramView, int paramInt1,
int paramInt2, int paramInt3, int paramInt4, int paramInt5,
int paramInt6, int paramInt7, int paramInt8) {
int y = 0;
for(int x=0; x< indexLine; x++){
y += layout.getChildAt(x).getHeight();
}
makeScroll(y);
}
});
}
private void makeScroll(final int go){
scrollRegole.post(new Runnable() {
public void run() {
scroll.scrollTo(0, go);
}
});
}
here if i want to show lines[3] (for exsampe..) i know the correct height. My problem now is remove space between TextView.. but it works!
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.
Java class:
public class ImageViewHelper extends android.support.v7.widget.AppCompatImageView {
public ImageViewHelper(Context context) {
super(context);
}
public ImageViewHelper(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ImageViewHelper(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
Drawable d = getDrawable();
if (d != null) {
int w = MeasureSpec.getSize(widthMeasureSpec);
int h = w * d.getIntrinsicHeight() / d.getIntrinsicWidth();
setMeasuredDimension(w, h);
}
else super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
XML:
<com.example.app.ImageViewHelper
android:id="#+id/img"
android:src="#drawable/start"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:adjustViewBounds="true" />
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;

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:

return super.onInterceptTouchEvent(event);

return false;
}
public void setPagingEnabled(boolean enabled) {

ExtendedPagerTabStrip:

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
