ViewGroupがクラッシュするアプリケーション

Question

私はGitHub hereを使用しています。これにより、イメージビューで簡単にズームインできます。しかし、ImageViewがViewGroup内にあるとアプリがクラッシュする問題があります。そこで彼らは回避策を提案しました。私は回避コードを自分のプロジェクトに実装したとき、それは仕事をしませんでした。

候補]コード：

import android.content.Context; 
import android.util.AttributeSet; 
import android.view.MotionEvent; 

import com.mxn.soul.flowingdrawer_core.LeftDrawerLayout; 

/** 
* Created by user on 2016-06-28. 
*/ 
public class HackyProblematicViewGroup extends LeftDrawerLayout { 

public HackyProblematicViewGroup(Context context, AttributeSet attrs) { 
    super(context, attrs); 
} 

@Override 
public boolean onInterceptTouchEvent(MotionEvent ev) { 
    try { 
     return super.onInterceptTouchEvent(ev);//The error first goes here then to the LeftDrawerLayout on the bottom! 
    } catch (IllegalArgumentException e) { 
     //uncomment if you really want to see these errors 
     //e.printStackTrace(); 
     return false; 
    } 
} 
}

私はコードが間違っていたり、追加のですか？

また、LeftDrawerLayoutクラスはここthis GitHubのから来ているとエラーのコードの別の行もこれに行く：

public class LeftDrawerLayout extends ViewGroup { 
... 
    @Override 
public boolean onInterceptTouchEvent(MotionEvent ev) { 
    return mHelper.shouldInterceptTouchEvent(ev); 
} 
... 

このアプリはネクサス6 V6.0.1上でテストされて

ArrayIndexOutOfBoundsExceptionIllegalArgumentExceptionのサブクラスではありません。例外を実際にキャッチしたい場合は、IllegalArgumentExceptionをExceptionに置き換えることができます。
