一、Fragment静态使用

1.蓝色布局：blue.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@color/colorPrimary"
                android:orientation="vertical" >    <TextView
        android:id="@+id/blue_tv"
        android:layout_centerInParent="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:text="蓝色Fragment"
        /></RelativeLayout>

2.黄色布局：yellow.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
                android:background="@color/yellow"
              android:orientation="vertical" >    <TextView
        android:id="@+id/yellow_tv"
        android:layout_centerInParent="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:text="黄色Fragment"
        /></RelativeLayout>

3.黄色Fragment：YellowFragment.java

 */public class YellowFragment extends Fragment {    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {        return inflater.inflate(R.layout.yellow, container, false);
    }
}

4.绿色Fragment：BlueFragment.java

 * 邮箱：1981462002@qq.com<br/>
 * 说明：绿色Fragment
 */public class BlueFragment extends Fragment {    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {        
        return inflater.inflate(R.layout.fragment_bottom, container, false);
    }
}

5.主布局：layout/activity_static.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".activity.ActFragmentActivity">

    <fragment
        android:id="@+id/yellow_fragment1"

        android:name="com.toly1994.avi_fragment.staticFg.YellowFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <View
        android:background="@color/gray_8f"
        android:layout_width="match_parent"
        android:layout_height="1dp"/>

    <fragment
        android:id="@+id/yellow_fragment2"

        android:name="com.toly1994.avi_fragment.staticFg.YellowFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>

    <fragment
        android:id="@+id/blue_fragment"
        android:name="com.toly1994.avi_fragment.staticFg.BlueFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="4"/></LinearLayout>

6.使用：StaticFragmentActivity.java

public class StaticFragmentActivity extends AppCompatActivity {    @Override
    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_static);
    }
}

二、动态使用

public class ActFragmentActivity extends FragmentActivity {    @Override
    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_acti);
        initFragment();
    }    /**
     * 动态加载Fragment
     */
    private void initFragment() {
        FragmentManager fm = getFragmentManager();//1.获取FragmentManager
        FragmentTransaction ft = fm.beginTransaction();//2.fm开启事务
        //3.动态添加 （控件id,fragment对象）
        ft.add(R.id.fl_title, new YellowFragment());
        ft.add(R.id.fl_content, new BlueFragment());
        ft.commit();//4.提交事务
    }
}
