我每隔一行写了一个System.out，发现前面的代码都运行了，最后的show()没运行。
下面是代码及logcat内容：
PopupMenu popupMenu = new PopupMenu(getBaseContext(), view, 10);
popupMenu.getMenuInflater().inflate(R.menu.list_of_popup_menu, popupMenu.getMenu());
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()) {
case R.id.hello:
Toast.makeText(getBaseContext(), "hello", Toast.LENGTH_SHORT).show();
case R.id.world:
Toast.makeText(getBaseContext(), "world", Toast.LENGTH_SHORT).show();
}
return true;
}
});
popupMenu.show();
mypopupmenu W/art: Before Android 4.1, method int android.support.v7.widget.ListViewCompat.lookForSelectablePosition(int, boolean) would have incorrectly overridden the package-private method in android.widget.ListView
mypopupmenu I/ListPopupWindow: Could not find method setEpicenterBounds(Rect) on PopupWindow. Oh well.
