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; 
      } 
    } 
 
  }; 
}
