我正在尝试使用以下代码来侦听来自服务的触摸事件
public void onCreate() {
super.onCreate();
// Toast.makeText(getBaseContext(),"onCreate", Toast.LENGTH_LONG).show();
mView = new HUDView(this);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
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(mView, params);
}
@Override
public boolean onTouchEvent(MotionEvent ev) {
//return super.onTouchEvent(event);
final int action = ev.getAction();
// switch (action & MotionEvent.ACTION_MASK) {
// case MotionEvent.ACTION_DOWN: {
final float x = ev.getX();
final float y = ev.getY();
Points p = new Points();
p.setPoints(x,y);
list.add(p);
return true;
}
此代码在Android ver 2.3上运行完美,但在版本4.0和4.1中未调用onTouchEvent。可能是什么问题
我正在尝试从服务中侦听点击,服务附加了一个Activity。该活动照常使用,但服务保持记录点击。当使用TYPE_SYSTEM_OVERLAY时,它在Android 2.3上工作得很好,但在4.1上没有调用onTouchEvent。使用TYPE_SYSTEM_ALERT时,会调用onTouchEvent,但触摸事件不会传递给活动,并且无法响应。
答案 0 :(得分:0)
试试这个:
findViewById(R.id.someView).setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent ev) {
final int action = ev.getAction();
final float x = ev.getX();
final float y = ev.getY();
Points p = new Points();
p.setPoints(x,y);
list.add(p);
return true;
}
});
