前文 Android超出父布局控件点击事件失效问题处理 讲了当使用 clipChildren=false 属性时，超出父控件的子控件区域点击会失效的问题，也给出了解决方案，但是觉得还不够方便，就封装了一个 GlobalTouchActivity 基类，以便于使用。

• 代码如下

  package com.game.win.xxx.sdk.pages.ui;
  
  import android.app.Activity;
  import android.graphics.Point;
  import android.graphics.Rect;
  import android.os.Bundle;
  import android.view.MotionEvent;
  import android.view.View;
  
  import androidx.annotation.Nullable;
  
  import com.game.win.wallet.sdk.utils.ViewUtils;
  
  import java.util.HashMap;
  import java.util.Iterator;
  import java.util.Map;
  import java.util.Set;
  
  public class GlobalTouchActivity extends Activity {
  
      @Override
      protected void onCreate(@Nullable Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          supportGlobalTouchListener();
      }
  
      /**
       * 全局点击事件监听
       */
      public interface OnGlobalTouchListener{
          /**
           * 监听事件回调
           * @param rect View所在坐标范围
           * @param point 点击事件发生的坐标
           */
          void onTouch(Rect rect, Point point);
      }
  
      final Map<View,OnGlobalTouchListener> globalTouchViews = new HashMap<>();
  
  
      /**
       * 支持全局触摸事件监听
       */
      public void supportGlobalTouchListener(){
          getWindow().getDecorView().getRootView().setOnTouchListener(new View.OnTouchListener() {
              @Override
              public boolean onTouch(View v, MotionEvent event) {
                  Set<Map.Entry<View, OnGlobalTouchListener>> touchViewSet = globalTouchViews.entrySet();
                  Iterator<Map.Entry<View, OnGlobalTouchListener>> it = touchViewSet.iterator();
                  while(it.hasNext()){
                      Map.Entry<View, OnGlobalTouchListener> entry = it.next();
                      View view = entry.getKey();
                      if(globalTouch(view,event)){
                          Rect rect = new Rect();
                          view.getGlobalVisibleRect(rect);
                          OnGlobalTouchListener globalTouchListener = entry.getValue();
                          if(globalTouchListener!=null){
                              globalTouchListener.onTouch(rect,new Point((int)event.getRawX(),(int)event.getRawY()));
                          }
                          return true;
                      }
                  }
                  return false;
              }
          });
      }
  
      /**
       * 设置全局触摸事件监听
       * @param view
       * @param listener
       */
      public void setGlobalTouchListener(View view,OnGlobalTouchListener listener){
          globalTouchViews.put(view,listener);
      }
  
      /**
       * 全局坐标点击判断
       * @param targetView
       * @param event
       * @return
       */
      private boolean globalTouch(View targetView, MotionEvent event) {
          if(event.getAction() == MotionEvent.ACTION_UP){
              Rect r = new Rect();
              targetView.getGlobalVisibleRect(r);
              int x = (int) event.getRawX();
              int y = (int) event.getRawY();
              return r.contains(x,y);
          }
          return false;
      }
      
      @Override
      public void onDetachedFromWindow() {
          globalTouchViews.clear();
          super.onDetachedFromWindow();
      }
  }

  这样一来，当需要处理全局事件点击时，直接继承自 GlobalTouchActivity ，然后设置全局触摸点击事件，就变得非常简单了：

  setGlobalTouchListener(center_icon, new OnGlobalTouchListener() {
      @Override
      public void onTouch(Rect rect, Point point) {
          finish();
      }
  });
