how over android navigation android studio with canvas?

i find this canvas that allows you to write geometrics form in your layout , i use this to cover the android status bar and the android notification bar and it worked so right now i want to cover , with another rectangle , the navigation bar but i can't achieve this goal.
i tried to change the hight of the top of the rectangle to be at the bottom of the screen but it didn't work because the rectangle remains at the top of the screen.
can you help me to move this rectangle to the bottom?
this is my customViewGroup :
package com.liliumduva;

public class CustomViewGroup extends ViewGroup {
public CustomViewGroup(Context context) {
super(context);
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint paint = new Paint();
// paint.setColor(Color.RED);
//canvas.drawRect(0, 0, getWidth(), getHeight() / 10, paint);
Rect rect = new Rect();
paint.setColor(Color.BLUE);
rect.left = 0;
rect.top = getHeight() - getHeight() / 10 - getStatusBarHeight();
rect.right = getWidth();
rect.bottom = getHeight() - getResources().getDimensionPixelSize(getResources().getIdentifier("navigation_bar_height", "dimen", "android"));
canvas.drawRect(rect, paint);
}
private int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
#Override

PinchToZoom not working with multiple activities in Android

I am trying to implement pinch to zoom, in my project i have used multiple activities which interconnect them. Initially when i had my complete project in one activity it was performing zoom, however it is not the case with multiple activities.

Use the below code for Pinch Zoom.
ScaleGestureDetector detector = new ScaleGestureDetector(this, new ScaleListener());
private class ScaleListener extends
ScaleGestureDetector.SimpleOnScaleGestureListener {
#Override
public boolean onScale(ScaleGestureDetector detector) {
scaleFactor *= detector.getScaleFactor();
scaleFactor = (scaleFactor < 1 ? 1 : scaleFactor);
scaleFactor = ((float) ((int) (scaleFactor * 100))) / 100;
view.setScaleX(scaleFactor);
view.setScaleY(scaleFactor);
return true;
}
}
Also,Setup a touchListener to you view on onCreate(The one which you want to zoom).
example
(YOUR_VIEW).setClickable(true);
(YOUR_VIEW).setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
MainActivity.this.view = v;
detector.onTouchEvent(event);
return false;
});
Hope this will help :)
UPDATE 1:
Based on your code.change condition like this
imageView1.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
} else {
Main2Activity.this.view = v;
detector.onTouchEvent(event);
}
return false;
}
});

How to start popupwindow from service in android?

I wish to create a floating button which will hover over the entire Android screen. When the button or hovering icon is clicked, it should open a small popupwindow.
I was able to create the hovering icon using service class however I am unable to launch popupwindow. Whenever I click the floating icon, the error log says:
Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not valid; is your activity running?

You should not do these ui operations in your service class. Because after you show your button service instance will be removed and there is no context when you click the button. I think you should follow similar approach like below.
Service Class:
Intent activityIntent = new Intent(context, MainActivity);
activityIntent.putExtra("showPopup", true);
context.startActivity(activityIntent);
Activity Class:
onCreate(){
boolean showPopUp = getIntent().getBooleanExtra("showPopup", false);
if(showPopUp){
// Show your popup here
}
}
