我创建了一个运行服务的应用程序。该服务基本上有一个叠加按钮,点击按钮做了一些事情。但是,每次我点击按钮,按钮背景中的应用程序都会响应。请有人帮忙吗?
我已提到link。
这是我的代码:
服务代码:
public class HUD extends Service implements OnTouchListener{
Button mButton;
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
String s;
s = "Hari";
return null;
}
@Override
public void onCreate() {
super.onCreate();
//mView = new HUDView(this);
mButton = new Button(this);
mButton.setText("Overlay button");
mButton.setOnTouchListener(this);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.RIGHT | Gravity.TOP;
params.setTitle("Load Average");
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(mButton, params);
}
@Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(getBaseContext(),"onDestroy", Toast.LENGTH_LONG).show();
if(mButton != null)
{
((WindowManager) getSystemService(WINDOW_SERVICE)).removeView(mButton);
mButton = null;
}
}
@Override
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(this,"Overlay button event", Toast.LENGTH_SHORT).show();
return false;
}
}
清单也有以下许可:
我尝试将类型更改为
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
现在,无论我点击哪里,都会调用触摸事件。请有人帮帮我吗?

问题是您正在使用WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY。我认为,因为一些Android 4.x它不再可用了。这是我实现叠加按钮的方式:
public class OverlayButton extends Service implements OnTouchListener {
Button mButton;
WindowManager wm;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
mButton = new Button(this);
mButton.setText("Overlay button");
mButton.setTextColor(Color.BLACK);
mButton.setOnTouchListener(this);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(150,
150, WindowManager.LayoutParams.TYPE_PHONE, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
| WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, PixelFormat.TRANSLUCENT);
params.gravity = Gravity.LEFT | Gravity.CENTER;
wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(mButton, params);
}
@Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(getBaseContext(), "onDestroy", Toast.LENGTH_LONG).show();
if (mButton != null) {
((WindowManager) getSystemService(WINDOW_SERVICE)).removeView(mButton);
mButton = null;
}
}
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
Log.d("OverlayButton onTouch", "touched the button");
stopSelf();
}
return true;
}
}
我做的是,如果我触摸他,我也让他有能力再次消失。
这就是我让他出现的方式:
getActivity().startService(new Intent(getActivity().getBaseContext(), OverlayButton.class));
但是,如果你从Activity中启动它,只需使用:
startService(new Intent(this, OverlayButton.class));
不要忘记在清单中设置这些:
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
在标签内部也不要忘记:
<service android:name="OverlayButton" ></service>

当您使用此WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH
标记时,它会告诉应用监视您视图之外的所有内容。
请尝试使用WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
。这将仅截取您的观点。
要确认,您需要使用WindowManager.LayoutParams.TYPE_SYSTEM_ALERT
来使视图可点击。
