Android应用程序中的可拖动浮动窗口：不关注布局元素

Question

在我的应用程序中，我正在制作一个浮动类型窗口，该窗口出现在任何应用程序或主屏幕的顶部。就像 Facebook 聊天气泡一样。我用一些用于不同操作的按钮制作了浮动窗口拖动山墙。我在窗口中有一个编辑文本布局。我在关注浮动窗口时遇到一些问题。每个布局都没有焦点，编辑文本也不起作用。

我附上了相同的屏幕截图视频。

我的代码是：-

在服务中 oncreate(){}

    mFloatingWidget = LayoutInflater.from(this).inflate(R.layout.layout_floating_widget, null);
    int layoutType;
    if(Build.VERSION.SDK_INT < 26) {
        layoutType = WindowManager.LayoutParams.TYPE_PHONE;
    } else {
        layoutType = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
    }


    final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            layoutType,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.TRANSLUCENT);

    params.gravity = Gravity.TOP | Gravity.START;
    params.x = 0;   // Initial Position of window
    params.y = 100; // Initial Position of window
    mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
    mWindowManager.addView(mFloatingWidget, params);


    mFloatingWidget.findViewById(R.id.root_container).setOnTouchListener(new View.OnTouchListener() {
        private int initialX;
        private int initialY;
        private float initialTouchX;
        private float initialTouchY;
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Log.d("AD","Action E" + event);
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    Log.d("AD","Action Down");
                    initialX = params.x;
                    initialY = params.y;
                    initialTouchX = event.getRawX();
                    initialTouchY = event.getRawY();
                    return true;
                case MotionEvent.ACTION_UP:
                    Log.d("AD","Action Up");
                    int Xdiff = (int) (event.getRawX() - initialTouchX);
                    int Ydiff = (int) (event.getRawY() - initialTouchY);
                    if (Xdiff < 10 && Ydiff < 10) {
                        if (isViewCollapsed()) {
                            collapsedView.setVisibility(View.GONE);
                            expandedView.setVisibility(View.VISIBLE);
                        }
                    }
                    return true;
                case MotionEvent.ACTION_MOVE:
                    Log.d("AD","Action Move");
                    params.x = initialX + (int) (event.getRawX() - initialTouchX);
                    params.y = initialY + (int) (event.getRawY() - initialTouchY);
                    mWindowManager.updateViewLayout(mFloatingWidget, params);
                    return true;
            }
            return false;
        }
    });


}

请让我知道代码有什么问题。

谢谢

发生这种情况是因为焦点没有设置到窗口管理器，而是设置在主屏幕窗口上。为了防止这种情况，不要在参数中添加 FLAG_NOT_FOCUSABLE。

更新的代码：-

final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            layoutType,
            0,   // REMOVE FLAG_NOT_FOCUSABLE
            PixelFormat.TRANSLUCENT);

params.gravity = Gravity.TOP | Gravity.START;
params.x = 0;   // Initial Position of window
params.y = 100; // Initial Position of window
mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
mWindowManager.addView(mFloatingWidget, params);

希望这能回答您的疑问。

谢谢
