自定义代码

package com.duanlian.popupwindowdemo; 

import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.WindowManager;
import android.widget.LinearLayout;
import android.widget.PopupWindow;
import android.widget.TextView; 

/**
 * 自定义popupWindow
 */ 

public class RewritePopwindow extends PopupWindow {
  private View mView; 

  public RewritePopwindow(Activity context, View.OnClickListener itemsOnClick) {
    super(context);
    initView(context, itemsOnClick);
  } 

  private void initView(final Activity context, View.OnClickListener itemsOnClick) {
    LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    mView = mInflater.inflate(R.layout.popupwindow_share, null);
    LinearLayout weiXFriend = (LinearLayout) mView.findViewById(R.id.weixinghaoyou);
    LinearLayout friendster = (LinearLayout) mView.findViewById(R.id.pengyouquan);
    LinearLayout QQFriend = (LinearLayout) mView.findViewById(R.id.qqhaoyou);
    LinearLayout QQZone = (LinearLayout) mView.findViewById(R.id.qqkongjian);
    TextView canaleTv = (TextView) mView.findViewById(R.id.share_cancle);
    canaleTv.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) { 

        //销毁弹出框
        dismiss();
        backgroundAlpha(context, 1f);
      }
    });
    //设置按钮监听
    weiXFriend.setOnClickListener(itemsOnClick);
    friendster.setOnClickListener(itemsOnClick);
    QQFriend.setOnClickListener(itemsOnClick);
    QQZone.setOnClickListener(itemsOnClick);
    //设置SelectPicPopupWindow的View
    this.setContentView(mView);
    //设置SelectPicPopupWindow弹出窗体的宽
    this.setWidth(WindowManager.LayoutParams.FILL_PARENT);
    //设置SelectPicPopupWindow弹出窗体的高
    this.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
    //设置SelectPicPopupWindow弹出窗体可点击
    this.setFocusable(true);
    //设置PopupWindow可触摸
    this.setTouchable(true);
    //设置非PopupWindow区域是否可触摸
//    this.setOutsideTouchable(false);
    //设置SelectPicPopupWindow弹出窗体动画效果
//    this.setAnimationStyle(R.style.select_anim);
    //实例化一个ColorDrawable颜色为半透明
    ColorDrawable dw = new ColorDrawable(0x00000000);
    //设置SelectPicPopupWindow弹出窗体的背景
    this.setBackgroundDrawable(dw);
    backgroundAlpha(context, 0.5f);//0.0-1.0
    this.setOnDismissListener(new OnDismissListener() { 

      @Override
      public void onDismiss() {
        // TODO Auto-generated method stub
        backgroundAlpha(context, 1f);
      }
    });
  } 

  /**
   * 设置添加屏幕的背景透明度
   *
   * @param bgAlpha
   */
  public void backgroundAlpha(Activity context, float bgAlpha) {
    WindowManager.LayoutParams lp = context.getWindow().getAttributes();
    lp.alpha = bgAlpha;
    context.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
    context.getWindow().setAttributes(lp);
  } 

}

MainActivity中用

package com.duanlian.popupwindowdemo; 

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Gravity;
import android.view.View;
import android.widget.Toast; 

public class MainActivity extends AppCompatActivity {
  private RewritePopwindow mPopwindow; 

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    findViewById(R.id.share).setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View view) {
        mPopwindow = new RewritePopwindow(MainActivity.this, itemsOnClick);
        mPopwindow.showAtLocation(view,
            Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);
      }
    });
  } 

  //为弹出窗口实现监听类
  private View.OnClickListener itemsOnClick = new View.OnClickListener() { 

    public void onClick(View v) {
      mPopwindow.dismiss();
      mPopwindow.backgroundAlpha(MainActivity.this, 1f);
      switch (v.getId()) {
        case R.id.weixinghaoyou:
          Toast.makeText(MainActivity.this, "微信好友", Toast.LENGTH_SHORT).show();
          break;
        case R.id.pengyouquan:
          Toast.makeText(MainActivity.this, "朋友圈", Toast.LENGTH_SHORT).show();
          break;
        case R.id.qqhaoyou:
          Toast.makeText(MainActivity.this, "QQ好友", Toast.LENGTH_SHORT).show();
          break;
        case R.id.qqkongjian:
          Toast.makeText(MainActivity.this, "QQ空间", Toast.LENGTH_SHORT).show();
          break;
        default:
          break;
      }
    } 

  };
}
