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。ViewGroupがクラッシュするアプリケーション
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
キャッチを「例外」に変更すると、まだエラーが表示されます –
私は実際に何か他のものを修正し、このコードを使ってオリジナルの問題を修正しました!ありがとうございました! (見ている人のための私の修正の詳細な説明は、[this](https://github.com/chrisbanes/PhotoView/issues/382)を参照してください) –
