I'm so tired doing this project
Im coding a project that show head-chat like Facebook
But when I add view to window manager, it don't show the head chat and crash
Please help me
MainActivity.java:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.start_bubble).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startService(new Intent(MainActivity.this, ChatHeadService.class));
finish();
}
});
}
}
Here is my ChatHeadService.java code:
public class ChatHeadService extends Service {
private WindowManager mWindowManager;
private View mChatHeadView;
public ChatHeadService() {
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
//Inflate the chat head layout we created
mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
mChatHeadView = LayoutInflater.from(this).inflate(R.layout.layout_chat_head, null);
//Add the view to the window.
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
//Specify the chat head position
params.gravity = Gravity.TOP | Gravity.LEFT; //Initially view will be added to top-left corner
params.x = 0;
params.y = 100;
//Add the view to the window
mWindowManager.addView(mChatHeadView, params);
//Set the close button.
ImageView closeButton = (ImageView) mChatHeadView.findViewById(R.id.close_btn);
closeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//close the service and remove the chat head from the window
stopSelf();
}
});
//Drag and move chat head using user's touch action.
final ImageView chatHeadImage = (ImageView) mChatHeadView.findViewById(R.id.chat_head_profile_iv);
chatHeadImage.setOnTouchListener(new View.OnTouchListener() {
private int lastAction;
private int initialX;
private int initialY;
private float initialTouchX;
private float initialTouchY;
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
//remember the initial position.
initialX = params.x;
initialY = params.y;
//get the touch location
initialTouchX = event.getRawX();
initialTouchY = event.getRawY();
lastAction = event.getAction();
return true;
case MotionEvent.ACTION_UP:
//As we implemented on touch listener with ACTION_MOVE,
//we have to check if the previous action was ACTION_DOWN
//to identify if the user clicked the view or not.
if (lastAction == MotionEvent.ACTION_DOWN) {
//Open the chat conversation click.
Intent intent = new Intent(ChatHeadService.this, ChatActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
//close the service and remove the chat heads
stopSelf();
}
lastAction = event.getAction();
return true;
case MotionEvent.ACTION_MOVE:
//Calculate the X and Y coordinates of the view.
params.x = initialX (int) (event.getRawX() - initialTouchX);
params.y = initialY (int) (event.getRawY() - initialTouchY);
//Update the layout with new X & Y coordinate
mWindowManager.updateViewLayout(mChatHeadView, params);
lastAction = event.getAction();
return true;
}
return false;
}
});
}
@Override
public void onDestroy() {
super.onDestroy();
if (mChatHeadView != null) mWindowManager.removeView(mChatHeadView);
}
}
And here is my log:

First you need to verify target device then it will work . here is sample code according to your service ,it will work fine.
