    背景

    在做一个设置页面的时候,通过PreferenceCategory来动态添加SwitchPreference来做设置,但是QA反馈说容易误触修改状态,需要对其进行优化

    分析

    https://blog.csdn.net/vipclx/article/details/8493900 通过该篇文章分析,然后并不适用,通过查看源码并没有好的处理方式。
    先开始从SwitchPreference各个视图做点击事件屏蔽,先重写onBindViewHolder函数,对itemView进行点击事件置空

    点击事件回调2次问题处理

    通过打印调用栈

    仅需继承SwitchPreference是屏蔽onClick函数就行

    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();
        }
