本文实例自定义PopupWindow，点击弹出PopupWindow，背景变暗，仿点击弹出分享功能，供大家参考，具体内容如下
注:参照大神代码写的
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; } } }; }
