Question

我有这个截图应用程序，它在自己的活动中运行良好。但我希望它能捕获任何屏幕或任何其他应用程序的活动，甚至在游戏中。因此，我将它实例化为服务，但它失败了。这是代码：

public class CaptureService extends Service {


private ImageView c_icon;
private View m_icon;
private WindowManager wm, wmm;
private GestureDetectorCompat clik_detector;
private RelativeLayout rel;  

public void onCreate()
{
    super.onCreate();
    icon_pop();

    clik_detector = new GestureDetectorCompat(this, new IconGestureListener());

}

创建了一个窗口管理器，以便它可以保存捕获徽标：

private void icon_pop()
{
    wm = (WindowManager) getSystemService(WINDOW_SERVICE);

    c_icon = new ImageView(this);
    c_icon.setImageResource(R.drawable.c_icon);
    c_icon.setClickable(true);
    c_icon.setEnabled(true);


    final WindowManager.LayoutParams iconparam = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_PHONE,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.TRANSPARENT);

    iconparam.gravity = Gravity.TOP | Gravity.LEFT;
    iconparam.x = 0;
    iconparam.y = 0;

    wm.addView(c_icon, iconparam);


    c_icon.setOnTouchListener(new View.OnTouchListener() {
        private WindowManager.LayoutParams icon_param = iconparam;
        private int initialX;
        private int initialY;
        private float initialTouchX;
        private float initialTouchY;

        @Override
        public boolean onTouch(View v, MotionEvent e) {
            clik_detector.onTouchEvent(e);
            switch (e.getAction()) 
            {
            case MotionEvent.ACTION_DOWN:
                initialX = icon_param.x;
                initialY = icon_param.y;
                initialTouchX = e.getRawX();
                initialTouchY = e.getRawY();
                break;
            case MotionEvent.ACTION_UP:

                break;
            case MotionEvent.ACTION_MOVE:
                icon_param.x = initialX + (int) (e.getRawX() - initialTouchX);
                icon_param.y = initialY + (int) (e.getRawY() - initialTouchY);
                wm.updateViewLayout(c_icon, icon_param);                    
                break;
            }
            return false;
        }
    });
}

但是当我实现触摸事件时，它只捕获窗口管理器内的空间，即仅捕获徽标。

public boolean onTouchEvent(MotionEvent event)
{
    this.clik_detector.onTouchEvent(event);
    return true;
}

class IconGestureListener extends GestureDetector.SimpleOnGestureListener
{

    @Override
    public boolean onDown(MotionEvent e) {

        return super.onDown(e);
    }

    @Override
    public boolean onDoubleTap(MotionEvent e) {
        // TODO Auto-generated method stub
        return super.onDoubleTap(e);
    }

    @Override
    public boolean onSingleTapConfirmed(MotionEvent e) {
        View rootView = findViewById(android.R.id.content).getRootView();
    rootView.setDrawingCacheEnabled(true);
    Bitmap bitmap = rootView.getDrawingCache();
    saveBitmap(bitmap);
    Toast.makeText(getApplicationContext(), "Successfully saved", Toast.LENGTH_SHORT).show();
        return super.onSingleTapConfirmed(e);
    }

}

如何拍摄每个屏幕或任何应用或游戏的每项活动的屏幕截图提前谢谢

Android屏幕截图应用无法捕获其自身活动之外的任何屏幕
