我希望捕获用户触摸事件的坐标(为此我实现了onTouch
方法),但我还希望在用户触摸屏幕时显示上下文菜单。
当使用onTouch
和onCreateContextMenu
方法时,每个触摸事件都会发送到onTouch
方法。永远不会调用onCreateContextMenu
方法。我想这是预料之中的。然后我尝试通过openContextMenu(v)
方法调用onTouch
来手动显示上下文菜单,这样可行,但在onContextItemSelected(MenuItem item)
调用后菜单不会从屏幕上消失。那么我怎样才能做到这一点呢?
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.record_match);
myCourtView = new MyImageView(getApplicationContext());
ll = (LinearLayout)findViewById(R.id.linearLayout);
ll.addView(myCourtView, new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
registerForContextMenu(myCourtView);
myCourtView.requestFocus();
myCourtView.setOnTouchListener(this);
}// End OnCreate
// Implement the OnClickListener callback
public boolean onTouch(View v, MotionEvent event) {
//do something when user interacts with the court view
myCourtView.processEvent(event);
openContextMenu(v);
myCourtView.invalidate();
return true;
}//End OnClickListener
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.shot_entry_menu, menu);
}//End onCreateContextMenu
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch (item.getItemId()) {
case R.id.player_1:
//do something
return true;
case R.id.player_2:
//do something else
return true;
}
return true;
}//End onContextItemSelected

你应该在onTouch中返回false:
如果监听器已经使用了该事件,则为true,否则为false。

对我来说,这个解决方案有效:
myCourtView.setOnTouchListener(new OnTouchListener()
{public boolean onTouch(View v, MotionEvent ev)
{});
休息是一样的

在返回true之后尝试将它放在公共布尔值onTouch中; registerForContextMenu(this.getListView());
