import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.WindowManager;
import android.widget.LinearLayout;

/**

*/
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;
