logcat的拆卸的FrameLayout main_activity.xml

<android.support.v4.widget.DrawerLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/drawer_layout" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 



<LinearLayout 
    android:layout_width="fill_parent"

MainActivity.java：

if(position!=0){ 
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(0,0,0); 
    // framelayout is child of linearlayout 


getSupportFragmentManager().findFragmentById(R.id.frame_container_slider).getView().setLayoutParams(lp); 
     }

請從婁代碼改變您的主要活動代碼。

if (position != 0) { 
    FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(0,0,0); 
    getSupportFragmentManager().findFragmentById(R.id.frame_container_slider) 
           .getView() 
           .setLayoutParams(lp); 
}
