Question

我已在Service中使用WindowManager，并且尝试从this发布和其他发布中查找解析，但是我仍然收到此错误消息。

无法添加窗口android.view.ViewRootImpl$W@b285d2e-此窗口类型的权限被拒绝

我已经在我的Manifest.xml上使用android.permission.SYSTEM_ALERT_WINDOW <---当前版本，或者 android.permission.INTERNAL_SYSTEM_WINDOW（此系统应用程序只能使用）

我的最低SDK为API 17。

错误按摩：

我的服务：（我的意思是这段代码来自下载示例项目）

public class FloatingWindow extends Service {

    WindowManager wm;
    LinearLayout ll;

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        super.onCreate();

        wm = (WindowManager) getSystemService(WINDOW_SERVICE);

        ll = new LinearLayout(this);
        ll.setBackgroundColor(Color.RED);
        LinearLayout.LayoutParams layoutParameteres = new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT, 400);
        ll.setBackgroundColor(Color.argb(66,255,0,0));
        ll.setLayoutParams(layoutParameteres);

        final WindowManager.LayoutParams parameters = new WindowManager.LayoutParams(
                500, 200, WindowManager.LayoutParams.TYPE_PHONE,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                PixelFormat.TRANSLUCENT);
        parameters.gravity = Gravity.CENTER | Gravity.CENTER;
        parameters.x = 0;
        parameters.y = 0;

      Button     stop = new Button(this);
    stop.setText("Stop");
        ViewGroup.LayoutParams btnParameters = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT);
        stop.setLayoutParams(btnParameters);

        ll.addView(stop);
        wm.addView(ll, parameters);

        ll.setOnTouchListener(new View.OnTouchListener() {
            WindowManager.LayoutParams updatedParameters = parameters;
            double x;
            double y;
            double pressedX;
            double pressedY;

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                switch (event.getAction()) {
                    case MotionEvent.ACTION_DOWN:

                        x = updatedParameters.x;
                        y = updatedParameters.y;

                        pressedX = event.getRawX();
                        pressedY = event.getRawY();

                        break;

                    case MotionEvent.ACTION_MOVE:
                        updatedParameters.x = (int) (x + (event.getRawX() - pressedX));
                        updatedParameters.y = (int) (y + (event.getRawY() - pressedY));

                        wm.updateViewLayout(ll, updatedParameters);

                    default:
                        break;
                }

                return false;
            }
        });

        stop.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                wm.removeView(ll);
                stopSelf();
                System.exit(0);
            }
        });
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        stopSelf();
    }

}

我更喜欢/从this和this复制代码我将该代码复制了一段时间，在项目下载中已经有app-debug.apk（清单中使用android.permission.SYSTEM_ALERT_WINDOW），并且尝试正常运行，但是当我在项目中使用该代码时，我那错误的按摩。

我还必须使用什么权限？

这个问题已经由我自己解决
