Android ActionBar menu with vertical (rotated) text items based on Custom Action Provider

I am adding a menu to an action bar item. The menu will contain vertical text for each item. What the menu contains is not important. I basically just want to create my own view that will pop up when I press an action bar item. So for the purposes of this question, you could imagine my view as a big black box.
The image on the right was made with Gimp. It is what I am trying to do, not what I have accomplished yet.
What I have tried
In order to update an old app with the Material Design theme, I've been going through all the lessons in the Android documentation for adding the app bar. Since my vertical text menu doesn't fit the common cases, I have to make a custom Action Provider. The documentation does not provide a full example for a custom action provider, though. The best I could find was this Stack Overflow answer.
The best I have been able to do (with a black View representing my future menu) is shown in the following image:
The star in the image above currently has the action provider. However, the custom view gets clipped off within the action bar. How do I make it float over everything? Also, I don't want it appearing until I click on the action bar item. Currently, though, it just shows right away.
Code
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// setup toolbar
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
...
}
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_settings:
// User chose the "Settings" item, show the app settings UI...
return true;
case R.id.action_favorite:
// User chose the "Favorite" action, mark the current item
// as a favorite...
return true;
default:
// If we got here, the user's action was not recognized.
// Invoke the superclass to handle it.
return super.onOptionsItemSelected(item);
}
}

I would be glad to see an example of any fully functioning custom action provider that shows a view outside of the action bar frame.

If You didn't find Custom Action Provider based solution, may be You want use Custom Toolbar & PopupWindow-based workaround which means:
1) create custom Toolbar with ImageButton as menu button and replace ActionBar with it (like in that post of Machado);
2) create PopupWindow with custom layout for menu items with vertical text;
3) add onClickListener to ImageButton from p.1 which show PopupWindow from p.2.
Layout of custom Toolbar (action_bar.xml) may be something like:
<?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="?attr/actionBarSize"
android:layout_gravity="fill_horizontal"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:background="#color/colorPrimary"
android:elevation="4dp"
android:layout_height="?attr/actionBarSize">
</android.support.v7.widget.Toolbar>
</RelativeLayout>
Layout of MainActivity (activity_main.xml) which use it:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="#+id/activity_main"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="0dp"
tools:context="<your_package_name>.MainActivity">
<include
android:id="#+id/tool_bar"
layout="#layout/action_bar"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
android:layout_marginStart="31dp"
android:layout_below="#+id/tool_bar"
android:layout_alignParentStart="true"
android:layout_marginTop="31dp"/>
</RelativeLayout>
ImageButton as "main popup menu" button described in main_menu.xml file this way (more in this post of ASH):
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/menu_button"
android:icon="#drawable/ic_more_vert"
android:title=""
app:showAsAction="always"
app:actionViewClass="android.widget.ImageButton"/>
</menu>
For vertical text of menu items You can use, for example, custom View like VerticalLabelView from this of kostmo:
public class VerticalLabelView extends View {
private TextPaint mTextPaint;
private String mText;
private int mAscent;
private Rect text_bounds = new Rect();
final static int DEFAULT_TEXT_SIZE = 15;
public VerticalLabelView(Context context) {
super(context);
initLabelView();
}
public VerticalLabelView(Context context, AttributeSet attrs) {
super(context, attrs);
initLabelView();
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.VerticalLabelView);
CharSequence s = a.getString(R.styleable.VerticalLabelView_text);
if (s != null) setText(s.toString());
setTextColor(a.getColor(R.styleable.VerticalLabelView_textColor, 0xFF000000));
int textSize = a.getDimensionPixelOffset(R.styleable.VerticalLabelView_textSize, 0);
if (textSize > 0) setTextSize(textSize);
a.recycle();
}
private final void initLabelView() {
mTextPaint = new TextPaint();
mTextPaint.setAntiAlias(true);
mTextPaint.setTextSize(DEFAULT_TEXT_SIZE);
mTextPaint.setColor(0xFF000000);
mTextPaint.setTextAlign(Align.CENTER);
setPadding(3, 3, 3, 3);
}
public void setText(String text) {
mText = text;
requestLayout();
invalidate();
}
public void setTextSize(int size) {
mTextPaint.setTextSize(size);
requestLayout();
invalidate();
}
public void setTextColor(int color) {
mTextPaint.setColor(color);
invalidate();
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
mTextPaint.getTextBounds(mText, 0, mText.length(), text_bounds);
setMeasuredDimension(
measureWidth(widthMeasureSpec),
measureHeight(heightMeasureSpec));
}
private int measureWidth(int measureSpec) {
int result = 0;
int specMode = MeasureSpec.getMode(measureSpec);
int specSize = MeasureSpec.getSize(measureSpec);
if (specMode == MeasureSpec.EXACTLY) {
// We were told how big to be
result = specSize;
} else {
// Measure the text
result = text_bounds.height() + getPaddingLeft() + getPaddingRight();
if (specMode == MeasureSpec.AT_MOST) {
// Respect AT_MOST value if that was what is called for by measureSpec
result = Math.min(result, specSize);
}
}
return result;
}
private int measureHeight(int measureSpec) {
int result = 0;
int specMode = MeasureSpec.getMode(measureSpec);
int specSize = MeasureSpec.getSize(measureSpec);
mAscent = (int) mTextPaint.ascent();
if (specMode == MeasureSpec.EXACTLY) {
// We were told how big to be
result = specSize;
} else {
// Measure the text
result = text_bounds.width() + getPaddingTop() + getPaddingBottom();
if (specMode == MeasureSpec.AT_MOST) {
// Respect AT_MOST value if that was what is called for by measureSpec
result = Math.min(result, specSize);
}
}
return result;
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
float text_horizontally_centered_origin_x = getPaddingLeft() + text_bounds.width()/2f;
float text_horizontally_centered_origin_y = getPaddingTop() - mAscent;
canvas.translate(text_horizontally_centered_origin_y, text_horizontally_centered_origin_x);
canvas.rotate(-90);
canvas.drawText(mText, 0, 0, mTextPaint);
}
}
(NB: may be You need to customize paddings of VerticalLabelView: on line
result = text_bounds.height() + getPaddingLeft() + getPaddingRight() + 16;
add "+16" for better padding)
and attrs.xml for VerticalLabelView class:
<resources>
<declare-styleable name="VerticalLabelView">
<attr name="text" format="string" />
<attr name="textColor" format="color" />
<attr name="textSize" format="dimension" />
</declare-styleable>
</resources>
Layout for PopupWindow (menu_layout.xml) in this case might be like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/menu_root"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="#dimen/activity_horizontal_margin">
<<your_package_name>.VerticalLabelView
android:id="#+id/menu_item1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:textSize="18sp"
android:layout_margin="16dp"
android:padding="4dp"
android:text="Vertical menu item 1"/>
<<your_package_name>.VerticalLabelView
android:id="#+id/menu_item2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:textSize="18sp"
android:layout_margin="16dp"
android:padding="4dp"
android:text="Vertical menu item 2"/>
<<your_package_name>.VerticalLabelView
android:id="#+id/menu_item3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:textSize="18sp"
android:layout_margin="16dp"
android:padding="4dp"
android:text="Vertical menu item 3"/>
<<your_package_name>.VerticalLabelView
android:id="#+id/menu_item4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:textSize="18sp"
android:layout_margin="16dp"
android:padding="4dp"
android:text="Vertical menu item 4"/>
</LinearLayout>
And MainActivity class can be like:
public class MainActivity extends AppCompatActivity {
private static final String TAG = MainActivity.class.getSimpleName();
private Toolbar mToolbar;
private int mToolbarTitleColor;
private ImageButton mMainMenuButton;
private int mActionBarSize;
private PopupWindow mPopupMenu;
private int mTextSize = 48;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TypedValue tv = new TypedValue();
if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true)) {
mActionBarSize = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
}
mToolbarTitleColor = Color.WHITE;
mToolbar = (Toolbar) findViewById(R.id.toolbar);
mToolbar.setTitleTextColor(mToolbarTitleColor);
setSupportActionBar(mToolbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
Drawable menuIcon = ContextCompat.getDrawable(this, R.drawable.ic_more_vert);
menuIcon.setColorFilter(mToolbarTitleColor, PorterDuff.Mode.SRC_ATOP);
getMenuInflater().inflate(R.menu.main_menu, menu);
mMainMenuButton = (ImageButton) menu.findItem(R.id.menu_button).getActionView();
mMainMenuButton.setBackground(null);
mMainMenuButton.setImageDrawable(menuIcon);
mMainMenuButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mPopupMenu != null && mPopupMenu.isShowing()) {
mPopupMenu.dismiss();
}
mPopupMenu = createPopupMenu();
mPopupMenu.showAtLocation(v, Gravity.TOP | Gravity.RIGHT, 0, mActionBarSize);
}
});
return true;
}
public PopupWindow createPopupMenu() {
final PopupWindow popupWindow = new PopupWindow(this);
LayoutInflater inflater = getLayoutInflater();
View popupView = inflater.inflate(R.layout.menu_layout, null);
VerticalLabelView menuItem1 = (VerticalLabelView)popupView.findViewById(R.id.menu_item1);
menuItem1.setOnClickListener(mOnMenuItemClickListener);
menuItem1.setText("Vertical menu item 1");
menuItem1.setTextColor(Color.WHITE);
menuItem1.setTextSize(mTextSize);
VerticalLabelView menuItem2 = (VerticalLabelView)popupView.findViewById(R.id.menu_item2);
menuItem2.setOnClickListener(mOnMenuItemClickListener);
menuItem2.setText("Vertical menu item 2");
menuItem2.setTextColor(Color.WHITE);
menuItem2.setTextSize(mTextSize);
VerticalLabelView menuItem3 = (VerticalLabelView)popupView.findViewById(R.id.menu_item3);
menuItem3.setOnClickListener(mOnMenuItemClickListener);
menuItem3.setText("Vertical menu item 3");
menuItem3.setTextColor(Color.WHITE);
menuItem3.setTextSize(mTextSize);
VerticalLabelView menuItem4 = (VerticalLabelView)popupView.findViewById(R.id.menu_item4);
menuItem4.setOnClickListener(mOnMenuItemClickListener);
menuItem4.setText("Vertical menu item 4");
menuItem4.setTextColor(Color.WHITE);
menuItem4.setTextSize(mTextSize);
popupWindow.setFocusable(true);
popupWindow.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
popupWindow.setContentView(popupView);
return popupWindow;
}
private View.OnClickListener mOnMenuItemClickListener = new View.OnClickListener() {
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.menu_item1: {
Log.d(TAG, "menu_item1");
}
break;
case R.id.menu_item2: {
Log.d(TAG, "menu_item2");
}
break;
case R.id.menu_item3: {
Log.d(TAG, "menu_item3");
}
case R.id.menu_item4: {
Log.d(TAG, "menu_item4");
}
break;
default: {
}
}
if (mPopupMenu != null && mPopupMenu.isShowing()) {
mPopupMenu.dismiss();
}
}
};
}
Ultimatly, as result You should receive something like that:
P.S. Of course You need more elegant solution for createPopupMenu().

SlidingPanelLayout not work well from right to left in android

I am creating SlidingPanelLayout from right to left for the filter purpose.The panel work fine it come out from right side and does animation but when Animation is stop it directly go to left side full but I want the ratio is 70% means right side panel came out 70% of the total screen and when click again it goes to hind and full Activity is display.
When first time Animation is stop the side panel goes to left side in the screenshot .But I want it right side.
ScreenShot :
but i want to display it write side and when click again it will go right side and hide again.

Thanks in Advance.

I think I found the Solution. I am Creating the new Project.

Circular Reveal not working when FAB gravity is bottom

I am working on morphing a floating action button (FAB) to a toolbar and things work smoothly and perfectly with the following code:
layout file:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

android:layout_marginTop="#dimen/activity_vertical_margin"
android:layout_marginRight="#dimen/activity_vertical_margin"
android:layout_marginBottom="#dimen/activity_vertical_margin"
android:src="#drawable/ic_add" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
style="#style/ToolBarTheme"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="top"
android:layout_marginTop="#dimen/activity_vertical_margin"
android:layout_marginBottom="#dimen/activity_vertical_margin"
android:visibility="invisible"

</FrameLayout>
activity:
package sg.com.saurabh.designlibraryexpirements;

FloatingActionButton fab;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_toolbar_morph);
toolbar = (Toolbar) findViewById(R.id.toolbar);
fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(mFabClickListener);
}
private View.OnClickListener mFabClickListener = new View.OnClickListener() {

}
};
private void revealToolbar() {

int x = (int)fab.getX() + fab.getWidth()/2;
int y = (int)fab.getY() + fab.getHeight()/2;
Animator animator = ViewAnimationUtils.createCircularReveal(toolbar, x, y, 0, toolbar.getWidth())
.setDuration(400);
animator.setInterpolator(new FastOutLinearInInterpolator());
animator.start();
}
private void dismissToolbar() {
int x = (int)fab.getX() + fab.getWidth()/2;
int y = (int)fab.getY() + fab.getHeight()/2;
Animator animator = ViewAnimationUtils.createCircularReveal(toolbar, x, y, toolbar.getWidth(), 0)
.setDuration(400);
animator.setInterpolator(new LinearOutSlowInInterpolator());
animator.addListener(new Animator.AnimatorListener() {
#Override

}
},200);
}
#Override
public void onBackPressed() {
if(toolbar.getVisibility() == View.VISIBLE) {
dismissToolbar();
}
else
super.onBackPressed();
}
}
The circular reveal works as expected for the above layout. However thing break up when I change the layout_gravity of the fab and toolbar to bottom instead of top. The rotate animation works and then the toolbar just appears without the circular reveal animation. I am completely stumped by how that breaks the circular reveal animation.

The fix for you would be to replace:
private void revealToolbar() {
....
int x = (int)fab.getX() + fab.getWidth()/2;
int y = (int)fab.getY() + fab.getHeight()/2;
....
}
by
private void revealToolbar() {
...
int x = (int)fab.getX() + fab.getWidth()/2;
int y = fab.getHeight()/2;
...
}
The reason is that createCircularReveal is taking parameters centerY and centerX as coordinates of the center of the animating circle, relative to view (i.e. Toolbar, in our case).
See method ViewAnimationUtils.createCircularReveal definition:
........
* #param view The View will be clipped to the animating circle.
* #param centerX The x coordinate of the center of the animating circle, relative to
* <code>view</code>.
* #param centerY The y coordinate of the center of the animating circle, relative to
* <code>view</code>.
* #param startRadius The starting radius of the animating circle.
* #param endRadius The ending radius of the animating circle.

Implementing a slider (SeekBar) in Android

I want to implement a slider, which is basically two lines, one vertical and one horizontal, crossing where the screen is touched. I have managed to make one but I have to issues:
The slider is not very smooth, there is a slight delay when I'm moving the finger
If I place two sliders it is not multitouch, and I'd like to use both of them simultaneously
Here is the code:
public class Slider extends View {
private Controller controller = new Controller();
private boolean initialisedSlider;
private int sliderWidth, sliderHeight;
private Point pointStart;
private Paint white;
private int mode;
final static int VERTICAL = 0, HORIZONTAL = 1, BOTH = 2;
public Slider(Context context) {
super(context);
setFocusable(true);
// TODO Auto-generated constructor stub
}
public Slider(Context context, AttributeSet attrs) {
super(context, attrs);
setFocusable(true);
pointStart = new Point();
initialisedSlider = false;
mode = Slider.BOTH;
}
#Override
protected void onDraw(Canvas canvas) {
if(!initialisedSlider) {
initialisedSlider = true;
sliderWidth = getMeasuredWidth();
sliderHeight = getMeasuredHeight();
pointStart.x = (int)(sliderWidth/2.0);
pointStart.y = (int)(sliderHeight/2.0);
controller = new Controller(pointStart, 3);
white = new Paint();
white.setColor(0xFFFFFFFF);
}
canvas.drawLine(controller.getCoordX(),0,
controller.getCoordX(),sliderHeight,
white);
canvas.drawLine(0, controller.getCoordY(),
sliderWidth, controller.getCoordY(),
white);
}
public boolean onTouchEvent(MotionEvent event) {
int eventaction = event.getAction();
int X = (int)event.getX();
int Y = (int)event.getY();
switch (eventaction) {
case MotionEvent.ACTION_DOWN:
if(isInBounds(X,Y)) {
updateController(X, Y);
}
break;
case MotionEvent.ACTION_MOVE:
if(isInBounds(X,Y)) {
updateController(X, Y);
}
break;
case MotionEvent.ACTION_UP:
if(isInBounds(X,Y)) {
updateController(X, Y);
}
break;
}
invalidate();
return true;
}
private boolean isInBounds(int x, int y) {
return ((x<=(sliderWidth)) && (x>=(0))
&& (y<=(sliderHeight)) && (y>=(0)));
}
private void updateController(int x, int y) {
switch(mode) {
case Slider.HORIZONTAL:
controller.setCoordX(x);
break;
case Slider.VERTICAL:
controller.setCoordY(y);
break;
case Slider.BOTH:
controller.setCoordX(x);
controller.setCoordY(y);
break;
}
}
private class Controller {
private int coordX, coordY;
Controller() {
}
Controller(Point point, int width) {
setCoordX(point.x);
setCoordY(point.y);
}
public void setCoordX(int coordX) {
this.coordX = coordX;
}
public int getCoordX() {
return coordX;
}
public void setCoordY(int coordY) {
this.coordY = coordY;
}
public int getCoordY() {
return coordY;
}
}
}
And the XML file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<com.android.lasttest.Slider
android:id="#+id/slider"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="center_horizontal"
android:adjustViewBounds="true"/>
<com.android.lasttest.Slider
android:id="#+id/slider"
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_gravity="center_horizontal"
android:adjustViewBounds="true"/>
<com.android.lasttest.Slider
android:id="#+id/slider"
android:layout_width="200dp"
android:layout_height="200dp"
android:layout_gravity="center_horizontal"
android:adjustViewBounds="true"/>
</LinearLayout>

How to implement a SeekBar
Add the SeekBar to your layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/textView"
android:layout_margin="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<SeekBar
android:id="#+id/seekBar"
android:max="100"
android:progress="50"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
Notes
max is the highest value that the seek bar can go to. The default is 100. The minimum is 0. The xml min value is only available from API 26, but you can just programmatically convert the 0-100 range to whatever you need for earlier versions.
progress is the initial position of the slider dot (called a "thumb").
For a vertical SeekBar use android:rotation="270".
Listen for changes in code
public class MainActivity extends AppCompatActivity {
TextView tvProgressLabel;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// set a change listener on the SeekBar
SeekBar seekBar = findViewById(R.id.seekBar);
seekBar.setOnSeekBarChangeListener(seekBarChangeListener);
int progress = seekBar.getProgress();
tvProgressLabel = findViewById(R.id.textView);
tvProgressLabel.setText("Progress: " + progress);
}
SeekBar.OnSeekBarChangeListener seekBarChangeListener = new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
// updated continuously as the user slides the thumb
tvProgressLabel.setText("Progress: " + progress);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// called when the user first touches the SeekBar
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
// called after the user finishes moving the SeekBar
}
};
}
Notes
If you don't need to do any updates while the user is moving the seekbar, then you can just update the UI in onStopTrackingTouch.

For future readers!
Starting from material components android 1.2.0-alpha01, you have slider component
ex:
<com.google.android.material.slider.Slider
android:id="#+id/slider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:valueFrom="20f"
android:valueTo="70f"
android:stepSize="10" />
