背景
在做一個(gè)設(shè)置頁面的時(shí)候，通過PreferenceCategory來動(dòng)態(tài)添加SwitchPreference來做設(shè)置，但是QA反饋說容易誤觸修改狀態(tài)，需要對其進(jìn)行優(yōu)化
分析
https://blog.csdn.net/vipclx/article/details/8493900 通過該篇文章分析，然后并不適用，通過查看源碼并沒有好的處理方式。
先開始從SwitchPreference各個(gè)視圖做點(diǎn)擊事件屏蔽，先重寫onBindViewHolder函數(shù)，對itemView進(jìn)行點(diǎn)擊事件置空
點(diǎn)擊事件回調(diào)2次問題處理
通過打印調(diào)用棧

僅需繼承SwitchPreference是屏蔽onClick函數(shù)就行
示例
public class AppPreference extends SwitchPreference {
private static final String TAG = GlobalConstant.TAG + ".AppPreference";
public AppPreference(Context context) {
super(context);
}
public AppPreference(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public void onBindViewHolder(PreferenceViewHolder holder) {
super.onBindViewHolder(holder);
holder.itemView.setOnClickListener(null);
View.OnClickListener onClickListener = null;
try {
Field field = Preference.class.getDeclaredField("mClickListener");
field.setAccessible(true);
onClickListener = (View.OnClickListener)
field.get(this);
} catch (Exception e) {
Utils.logError(TAG, "onBindViewHolder", e);
}
if (onClickListener != null) {
View switchView = holder.findViewById(android.R.id.switch_widget);
switchView.setOnClickListener(onClickListener);
}
}
@Override
protected void onClick() {
//super.onClick();
}
