调用了OnCreateOptions，但未调用OnOptionsItemSelected

Question

我有一个xml，其中包含作为设置的菜单项，还有一个打开选项菜单的按钮，它正在工作，但当我在选项菜单中选择某个东西时，它不再被调用

这是我的密码
主要活动

private PopupMenu mPopupMenu;
ImageButton settings =  findViewById(R.id.buttonSettings);

mPopupMenu = new PopupMenu(this, settings);
MenuInflater menuInflater = mPopupMenu.getMenuInflater();
menuInflater.inflate(R.menu.main_settings, mPopupMenu.getMenu());
settings.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mPopupMenu.show();
}
});

@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_settings, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.menuNightMode) {
openDialog();
return true;
}
return super.onOptionsItemSelected(item);
}
public void openDialog() {
DialogNightMode dialogNightMode = new DialogNightMode();
dialogNightMode.show(getSupportFragmentManager(), "test");
}

这是Xml

<ImageButton
android:id="@+id/buttonSettings"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:layout_marginEnd="10dp"
android:layout_marginRight="10dp"
android:layout_marginBottom="17dp"
android:background="@color/transparent"
android:tint="@color/gray"
android:src="@drawable/ic_settings_black_24dp" />

菜单的Xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto">    
<item android:id="@+id/menuNightMode" android:title="@string/MainPageMenuNight" />
</menu>

Answer 1

您的代码缺少MenuItemClickListener，您需要将其设置为PopupMenu。

将其设置为低于

popup.show();
//Set on click listener for the menu
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
if(id == R.id.menuNightMode) {
openDialog();
}
return false;
}
});
