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();
    }
