问题描述
我有两个类似的按钮
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<Button
android:id="@+id/sync_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Sync"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
作为项目添加到菜单
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/toggle_item"
android:title=""
app:showAsAction="always"
app:actionLayout="@layout/switch_button"
/>
<item
android:id="@+id/sync_item"
android:title=""
app:showAsAction="always"
app:actionLayout="@layout/sync"
/>
</menu>
我使用
getMenuInflater().inflate(R.menu.menu_main, menu);
一切似乎都很好,但是当我单击应用程序时,什么都没有发生,因为从未调用过onOptionsItemSelected(MenuItem item)
Everything seems fine, but when i click in application, nothing happens as onOptionsItemSelected(MenuItem item) is never called
@Override
public boolean onOptionsItemSelected(MenuItem item) {
Integer test = item.getItemId();
switch (item.getItemId()) {
case R.id.toggle_item:
...
case R.id.sync_item:
...
return super.onOptionsItemSelected(item);
}
使用
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
final Menu m = menu;
final MenuItem item = menu.findItem(R.id.sync_button);
item.getActionView().setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
do_stuff;
}
});
return true;
}
菜单项:
<item
android:id="@+id/myswitch"
android:title=""
app:showAsAction="always"
app:actionLayout="@layout/toggle" />
活动布局必须实现:
android:clickable="false"
我的切换动作布局:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="false">
<ToggleButton
android:id="@+id/actionbar_service_toggle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOn="Discovery"
android:textOff="Favourite"
android:clickable="false"/>
</RelativeLayout>
