我遇到了同样的问题,我发现了这个:https://code.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort =&id=172425
经过一番尝试,我找到了如何实施适用于我的案例的解决方法:
public class MySwitchPreference extends SwitchPreference {
/**
* Construct a new SwitchPreference with the given style options.
*
* @param context The Context that will style this preference
* @param attrs Style attributes that differ from the default
* @param defStyle Theme attribute defining the default style options
*/
public MySwitchPreference(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
/**
* Construct a new SwitchPreference with the given style options.
*
* @param context The Context that will style this preference
* @param attrs Style attributes that differ from the default
*/
public MySwitchPreference(Context context, AttributeSet attrs) {
super(context, attrs);
}
/**
* Construct a new SwitchPreference with default style options.
*
* @param context The Context that will style this preference
*/
public MySwitchPreference(Context context) {
super(context, null);
}
@Override
protected void onBindView(View view) {
ViewGroup viewGroup= (ViewGroup)view;
setSwitchClickable(viewGroup);
super.onBindView(view);
}
private void setSwitchClickable(ViewGroup viewGroup) {
if (null == viewGroup) {
return;
}
int count = viewGroup.getChildCount();
for(int n = 0; n < count; ++n) {
View childView = viewGroup.getChildAt(n);
if(childView instanceof Switch) {
final Switch switchView = (Switch) childView;
switchView.setClickable(true);
return;
} else if (childView instanceof ViewGroup){
ViewGroup childGroup = (ViewGroup)childView;
setSwitchClickable(childGroup);
}
}
}
然后你只需要直接在 SwitchPreference 中使用你自己的“MySwitchPreference”。
