Android给控件添加触摸回调

效果图

实现方法

1. 重写RelativeLayout

package com.bitmain.btccom.view;

import android.content.Context;

import android.util.AttributeSet;

import android.view.MotionEvent;

import android.widget.RelativeLayout;

import com.bitmain.btccom.interfaces.BitmainOnTouchListener;

/**

 */

public class BitmainRelativeLayout extends RelativeLayout {

    private BitmainOnTouchListener mOnTouchListener;

    public BitmainRelativeLayout(Context context) {

        super(context);

    }

    public BitmainRelativeLayout(Context context, AttributeSet attrs) {

        super(context, attrs);

    }

    public BitmainRelativeLayout(Context context, AttributeSet attrs, int defStyleAttr) {

        super(context, attrs, defStyleAttr);

    }

    public void setOnTouchHandler(BitmainOnTouchListener onTouchListener) {

        mOnTouchListener = onTouchListener;

    }

    @Override

    public boolean dispatchTouchEvent(MotionEvent ev) {

        // 通知父控件是否将事件传递下来

        // getParent().requestDisallowInterceptTouchEvent(true);

        switch (ev.getAction()) {

            case MotionEvent.ACTION_DOWN:

                if (null != mOnTouchListener)

                    mOnTouchListener.onTouch();

        }

        return super.dispatchTouchEvent(ev);

    }

}

2. 触摸回调的接口

package com.bitmain.btccom.interfaces;

/**

 * Created by kongqw on 2016/1/29.

 */

public interface BitmainOnTouchListener {

    public void onTouch();

}

3. 使用

// 监听页面被触摸

BitmainRelativeLayout relativeLayout = (BitmainRelativeLayout) findViewById(R.id.relativeLayout);

relativeLayout.setOnTouchHandler(new BitmainOnTouchListener() {

    @Override

    public void onTouch() {

        // TODO 监听到控件被触摸 关掉PopupWindow

        ……

    }

});
