Question

我正在编写一个模拟鼠标的Android应用程序。我使用pocketmagic.com的代码进行光标覆盖在我的Droid Maxx（4.4.4）上它可以工作但是在Minix NEO X5 mini（4.4.2）（机顶盒）上它并没有这是代码

mView = new OverlayView(this);
    WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,//TYPE_SYSTEM_ALERT,//TYPE_SYSTEM_OVERLAY,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE |
                    WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN, //will cover status bar as well!!!
            PixelFormat.TRANSLUCENT);
    params.gravity = Gravity.LEFT | Gravity.TOP;
    params.setTitle("Cursor");
    WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
    wm.addView(mView, params);

和

class OverlayView extends ViewGroup {
private Paint mLoadPaint;
boolean mShowCursor;

Bitmap cursor;
public int x = 0,y = 0;

public void Update(int nx, int ny) {
    x = nx; y = ny;
}
public void ShowCursor(boolean status) {
    mShowCursor = status;
}
public boolean isCursorShown() {
    return mShowCursor;
}

public OverlayView(Context context) {
    super(context);
    cursor = BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_cursor);

    mLoadPaint = new Paint();
    mLoadPaint.setAntiAlias(true);
    mLoadPaint.setTextSize(10);
    mLoadPaint.setARGB(255, 255, 0, 0);
}

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    //canvas.drawText("Hello World", 0, 0, mLoadPaint);
    if (mShowCursor) canvas.drawBitmap(cursor,x,y,null);
}

@Override
protected void onLayout(boolean arg0, int arg1, int arg2, int arg3, int arg4) {
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    return true;
}

}

尝试降低API级别并降低SDK要求，看看它是否有效。

有覆盖窗口的麻烦
