您应该为此创建自定义视图。例如 ( layout/ab_custom.xml
):
<?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:layout_gravity="fill_horizontal" >
<ImageButton
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:src="@drawable/left" />
<ImageButton
android:id="@+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="@drawable/center" />
<ImageButton
android:id="@+id/btn3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="@drawable/right" />
</RelativeLayout>
然后在您的活动中onCreate
调用此方法:
private void showActionBar() {
LayoutInflater inflator = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.ab_custom, null);
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowHomeEnabled (false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setCustomView(v);
}
要控制您的项目,请使用以下命令:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.btn1:
//left button, do something
return true;
case R.id.btn2:
//center button
return true;
case R.id.btn3:
// right button
return true;
default:
return super.onOptionsItemSelected(item);
}
}
编辑:修改了我的答案。最好使用RelativeLayout as parent
.
