プログラムでRelativeLayoutを追加できません

Question

プログラムでRelativeLayoutを既存のxmlレイアウトに追加できません。 XMLレイアウトのみが表示されます。私のコードの共有

fragment_home.xml：

<RelativeLayout 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" 
tools:context="com.timetable.act.MainActivity$PlaceholderFragment" 
android:id="@+id/homeLayout" 
android:background="@color/white"> 


<ImageButton 
    android:layout_width="70dp" 
    android:layout_height="70dp" 
    android:layout_marginTop="380dp" 
    android:layout_marginLeft="240dp" 
    android:background="@drawable/circle" 
    android:id="@+id/addEvent" 
    android:src="@drawable/ic_mode_edit_white_24dp" 
    android:layout_gravity="right|bottom" 
    android:contentDescription="@string/hello" /> 
</RelativeLayout>

代わりに、実行中の相対的なレイアウトを作成するには、単純に作ることができます既存のものと、すべての子供が表示される...例：

あなたも、あなたがクリック可能なレイアウトがアクティブなときに、あなたが行うことができますになりたいレイアウトのボタンを持っている場合は

if (myCondition) { 
    myLayout = (RelativeLayout) myContext.findViewById(R.id.myLayoutID); 
    myLayout.setVisibilty(View.visible); 
    myLayoutTextView = (TextView) myContext.findViewById(R.id.myTextView); 
    myLayoutTextView.setVisibility(View.VISIBLE); 
} 

：

Button myButton = (Button) findViewById(R.id.myButton); 
myButton.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     if (myCondition) { 
      //Do Stuff Here 
     } 
});
