Android 实现长按弹出PopupMenu 菜单栏

在android中的sdk3.0版本以后加入了一个特殊的菜单效果，它可以在任何的view上显示，根据view的位置显示菜单效果。

res/menu/menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:id="@+id/send" android:title="发送邮件"></item>
  <item android:id="@+id/look" android:title="阅读邮件"></item>
  <item android:id="@+id/delete" android:title="删除邮件"></item>
</menu>

mainactivity.java

package com.zhangyu.mypopupmenu;
import android.os.bundle;
import android.support.v7.app.appcompatactivity;
import android.view.menuitem;
import android.view.view;
import android.widget.popupmenu;
import android.widget.textview;
import android.widget.toast;
public class mainactivity extends appcompatactivity {
  private textview tv1;
  private textview tv2;
  private textview tv3;
  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.activity_main);
    initview();
  }
  private void initview() {
    tv1 = (textview) findviewbyid(r.id.tv1);
    tv2 = (textview) findviewbyid(r.id.tv2);
    tv3 = (textview) findviewbyid(r.id.tv3);
    tv1.setonclicklistener(new view.onclicklistener() {
      @override
      public void onclick(view v) {
        mypopupmenu(v);
      }
    });
    tv2.setonclicklistener(new view.onclicklistener() {
      @override
      public void onclick(view v) {
        mypopupmenu(v);
      }
    });
    tv3.setonclicklistener(new view.onclicklistener() {
      @override
      public void onclick(view v) {
        mypopupmenu(v);
      }
    });
  }
  private void mypopupmenu(view v) {
    //定义popupmenu对象
    popupmenu popupmenu = new popupmenu(mainactivity.this, v);
    //设置popupmenu对象的布局
    popupmenu.getmenuinflater().inflate(r.menu.menu, popupmenu.getmenu());
    //设置popupmenu的点击事件
    popupmenu.setonmenuitemclicklistener(new popupmenu.onmenuitemclicklistener() {
      @override
      public boolean onmenuitemclick(menuitem item) {
        toast.maketext(mainactivity.this, "点击了----" + item.gettitle(), toast.length_short).show();
        return true;
      }
    });
    //显示菜单
    popupmenu.show();
  }
}
