Android開發手機選單(menu)按鍵的自定義
預設按下選單鍵顯示只有一個item,就是settings
1.新增item
開啟res\menu\main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.mmanager.MainActivity" >
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:title="@string/action_settings"
app:showAsAction="never"/>
<item //新新增的item
android:id="@+id/test"
android:orderInCategory="1"
android:title="test"
/>
</menu>
2.為新新增的item新增事件處理
在相應的activity.java中新增處理
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
else if(id==R.id.test)
{
System.out.println("按了test");
return true;
}
return super.onOptionsItemSelected(item);
}
