这是我的活动:
package src.go_letskerja.Fragment;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.app.AppCompatActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import src.go_letskerja.R;
/**
* A simple {@link Fragment} subclass.
*/
public class OtherFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_other, container, false);
((AppCompatActivity) getActivity()).getSupportActionBar().setTitle("TES");
//((AppCompatActivity)getActivity()).getSupportActionBar().setCustomView(R.layout.actionbar);
return v;
}
}
这是我的XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="60dp"
android:fitsSystemWindows="true"/>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="10dp"
android:paddingTop="10dp"
android:text="Tinggi Badan"
android:textSize="14dp" />
<TextView
android:id="@+id/tinggibadan"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="15dp"
android:paddingLeft="30dp"
android:paddingTop="10dp"
android:text="000 Cm"
android:textSize="20dp"
android:textStyle="bold" />
<TextView
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="@color/list" />
</LinearLayout>
推荐答案
是的，您可以将自定义工具栏添加到片段中，并在清单中没有操作栏的情况下创建活动主题，并执行类似的操作.这种布局可能是您的片段布局，并且会在您的活动中膨胀.
Yes, you can add the custom toolbar to your fragment and make your activity theme with no action bar in the Manifest and do something like this. this layout may be your fragment layout and inflate in your activity.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:layout_alignParentTop="true"
android:background="@color/colorPrimary"
android:gravity="top"
app:titleTextColor="@color/white">
<ImageView
android:id="@+id/iv_home"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:contentDescription="TODO"
android:visibility="visible"
app:srcCompat="@drawable/ic_back" />
<TextView
android:id="@+id/toolbar_title"
style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="List Entry"
android:textColor="@color/white"
android:textSize="@dimen/large_text_size" />
<ImageView
android:id="@+id/iv_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:layout_margin="@dimen/middium_padding"
android:contentDescription="TODO"
android:src="@mipmap/add"
android:visibility="visible" />
</android.support.v7.widget.Toolbar>
</RelativeLayout>
并使用片段视图访问您的工具栏.
and access you toolbar with framgment view.
