ListPreference android 2.3.3 setIcon：NoSuchMethodError

非常奇怪的bugListPreference android 2.3.3 setIcon：NoSuchMethodError

我在android上使用ListPreference。而在三星GIO S5660使用的setIcon（）方法爲它與Android 2.3.3當我已經有了：

怪事是，當我在的Nexus 7推出它，它工作正常。相同的代碼庫！

它有什麼問題？在API 11中添加

你檢查ListPreference文檔......下一次，請做一些研究befor問 – Selvin

這問題似乎是無關緊要的，因爲它沒有顯示研究的努力 –

你minising我。好。但最好給這個問題提供一些可用的解決方案。但是放置缺陷更容易。

這是ListPreference解決方案，可操作性較低，然後蜂窩的Android得：

public class IconPreference extends ListPreference { 

private Drawable mIcon; 

public IconPreference(Context context, AttributeSet attrs) { 
    this(context, attrs, 0); 
} 

public IconPreference(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs); 
    setLayoutResource(R.layout.icon_pref); 
    TypedArray a = context.obtainStyledAttributes(attrs, 
      R.styleable.IconPreference, defStyle, 0); 
    mIcon = a.getDrawable(R.styleable.IconPreference_icon); 
} 

@Override 
public void onBindView(View view) { 
    super.onBindView(view); 
    ImageView imageView = (ImageView) view.findViewById(R.id.icon); 
    if (imageView != null && mIcon != null) { 
     imageView.setImageDrawable(mIcon); 
    } 
} 

public void setIcon(Drawable icon) { 
    if ((icon == null && mIcon != null) || (icon != null && !icon.equals(mIcon))) { 
     mIcon = icon; 
     notifyChanged(); 
    } 
} 

public Drawable getIcon() { 
    return mIcon; 
}

}

的setIcon方法，因此，如果您嘗試它調用API < 11，那麼你將得到一個NoSuchMethodError
