Activity嵌套fragment

首先是单个fragment

activityfragment.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:background="@color/white"
    android:weightSum="2"
    android:orientation="vertical"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/con11"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">


    </FrameLayout>
    <FrameLayout
        android:id="@+id/con222"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">


    </FrameLayout>
</LinearLayout>

MyFragment,MytwoFragment

一定要是引入：import android.support.v4.app.Fragment;

public class MyFragment extends Fragment{

    protected View contentView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        contentView = inflater.inflate(R.layout.my_fragment, container, false);
        initViews();
        return contentView;

    }
    public void initViews(){

        TextView textView =(TextView)contentView.findViewById(R.id.myte11);
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(getContext(),"ssss",Toast.LENGTH_SHORT).show();
            }
        });
    }


}

Activityfragment

public class Activityfragment extends FragmentActivity {

    private Fragment contentFg;

    @Override
    protected void onCreate(Bundle arg0) {
        super.onCreate(arg0);
        setContentView(R.layout.activityfragment);
        switchContent();
    }

    public void switchContent() {
        //必需继承FragmentActivity,嵌套fragment只需要这行代码
        getSupportFragmentManager().beginTransaction().replace(R.id.con11, new MyFragment()).commitAllowingStateLoss();
        getSupportFragmentManager().beginTransaction().replace(R.id.con222, new MytwoFragment()).commitAllowingStateLoss();

    }
}

my_fragment.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:background="@color/white"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/myte11"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:text="sssssssssssssssss"/>

</LinearLayout>
