Android "アプリケーションが予期せず停止しました。もう一度お試しください。"

私の仕事のためにAndroidアプリを作っています。私は開発の初期段階でそれをテストしています。Android "アプリケーションが予期せず停止しました。もう一度お試しください。"

ここで日食コードです：

public class ClientFeedbackActivity extends Activity { 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    this.setContentView(R.Layout.main); 

    ImageButton mPortrait = (ImageButton)findViewById(R.id.imgPortrait); 
    mPortrait.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Toast.makeText(getBaseContext(), 
        "You have clicked the Portrait button", 
        Toast.LENGTH_SHORT).show();   
     } 
    }); 

    EditText mComments = (EditText)findViewById(R.id.txtComments); 
    mComments.setOnTouchListener(new View.OnTouchListener() { 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      // TODO Auto-generated method stub 
      return false; 
     } 
    }); 

    Button mSave = (Button)findViewById(R.id.btnSave); 
    mSave.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Toast.makeText(getBaseContext(), 
        "You have clicked the Save button", 
        Toast.LENGTH_SHORT).show(); 
     } 
    }); 


    Button mClear = (Button)findViewById(R.id.btnClear); 
    mClear.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Toast.makeText(getBaseContext(), 
        "You have clicked on the Clear button", 
        Toast.LENGTH_SHORT).show(); 
     } 
    }); 

    setContentView(R.layout.main); 
} 
}

おそらく、 'findViewById（）'の呼び出しの前に 'setContentView（）'コールを置こうとしますか？私はこれが解決策であるかどうかはわかりませんが、私は考えてみる価値があります。 – Bazzz

まずsetContentView()メソッドをonCreate()に呼び出してレイアウトを登録してから、findViewById()メソッドに電話する必要があります。

これが変更されました。私はそれがまだ動作していないことは恐れている。 – Matt

super.onCreate(savedInstanceState);

コンテンツを設定していないだけで、ImageButtonの前にsetContentView(R.layout.your_lauyout)が必要です。

コンテンツビューを設定する必要があります。それ以外の方法でレイアウトを取得する方法はありますか。また、例外処理をより良い方法で行うこともできます。

私はそれを変更しました。まだ動作していません。しかし、迅速な答えをありがとう。 – Matt

あなたはsetContentViewandの前にログを置いていましたか？それが動作していなくても、Eclipseを正常に閉じるか、IDEを再起動してください...もう一度アプリケーションを実行して、それを確認してください... – hossaindoula

私は考えましたそれを出す。レイアウトファイルにlayout_width属性を設定していませんでした。すべてソートされました。ありがとうございました。 – Matt

他の友人は、setContentView（R.layout.xxxxx）メソッドをプロジェクトに追加しました。私が言いたい1つの重要なことは、疑わしい方法の周りにtry-catchブロックを置くことです。これは例外の追跡に役立ちます（ある場合）。
