onCreateOptionsMenu对我没有做任何事情

Question

我完全不知道为什么会这样.选项菜单工作正常,但现在它已不再有效.

当我点击菜单按钮时,菜单打开,我点按它,什么也没有.当我做我的LogCat时它确实注册了MenuItem ...我真的要拉我的头发,我不明白为什么会这样.

下面是代码和xml

@Override
    public boolean onCreateOptionsMenu(Menu menu){
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.settings, menu);
        Log.d("MYTAG", "Clicked saved1");
        return super.onCreateOptionsMenu(menu);
    }



@Override
    public boolean onOptionsItemSelected(MenuItem item){
        Log.d("MYTAG", "Stupid clicker id="+item+" item id="+item.getItemId()+" id2="+R.mainmenuSettings.save1);
        switch(item.getItemId()){
        case R.mainmenuSettings.save1:
            Log.d("MYTAG", "Stupid clicker");
            break;
        }
        return super.onOptionsItemSelected(item);
    }


<?xml version="1.0" encoding="utf-8"?>
<menu
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item   android:id="@+mainmenuSettings/save1"
            android:title="save settings"/>
</menu>

Answer 1

菜单XML中存在错误."id"属性需要以"@ + id /"开头,所以这需要是"@ + id/mainmenuSettingsSave1"或类似的东西.此外,您需要在代码中将其引用为R.id.mainmenuSettingsSave1:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/mainmenuSettingsSave1"
          android:title="save settings"/>
</menu>

和

@Override
public boolean onCreateOptionsMenu(Menu menu){
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.settings, menu);
    Log.d("MYTAG", "Clicked saved1");
    return super.onCreateOptionsMenu(menu);
}



@Override
public boolean onOptionsItemSelected(MenuItem item){
    Log.d("MYTAG", "Stupid clicker id="+item+" item id="+item.getItemId()+" id2="+R.id.mainmenuSettingsSave1);
    switch(item.getItemId()){
    case R.id.mainmenuSettingsSave1:
        Log.d("MYTAG", "Stupid clicker");
        break;
    }
    return super.onOptionsItemSelected(item);
}
