Android中自定义PopupWindow实现弹出框并带有动画效果

public class LostPopupWindow extends PopupWindow {public Lost lost;public void onLost(Lost lost){this.lost = lost;}private View conentView;public View getConentView() {return conentView;}public LostPopupWindow(final Activity context) {LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);conentView = inflater.inflate(R.layout.lost_pop_menu, null);int h = context.getWindowManager().getDefaultDisplay().getHeight();int w = context.getWindowManager().getDefaultDisplay().getWidth();// 设置SelectPicPopupWindow的Viewthis.setContentView(conentView);// 设置SelectPicPopupWindow弹出窗体的宽this.setWidth(w / 2 + 50);// 设置SelectPicPopupWindow弹出窗体的高this.setHeight(LayoutParams.WRAP_CONTENT);// 设置SelectPicPopupWindow弹出窗体可点击this.setFocusable(true);this.setOutsideTouchable(true);// 刷新状态this.update();// 实例化一个ColorDrawable颜色为半透明ColorDrawable dw = new ColorDrawable(0000000000);// 点back键和其他地方使其消失,设置了这个才能触发OnDismisslistener ，设置其他控件变化等操作this.setBackgroundDrawable(dw);// mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);// 设置SelectPicPopupWindow弹出窗体动画效果this.setAnimationStyle(R.style.AnimationPreview);LinearLayout send = (LinearLayout) conentView.findViewById(R.id.send);LinearLayout mySend = (LinearLayout) conentView.findViewById(R.id.my_send);LinearLayout all = (LinearLayout) conentView.findViewById(R.id.all);send.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View arg0) {LostPopupWindow.this.dismiss();lost.onLost(2);}});mySend.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {LostPopupWindow.this.dismiss();lost.onLost(1);}});all.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {LostPopupWindow.this.dismiss();lost.onLost(0);}});}/*** 显示popupWindow** @param parent*/public void showPopupWindow(View parent) {if (!this.isShowing()) {// 以下拉方式显示popupwindowthis.showAsDropDown(parent, parent.getLayoutParams().width / 2, 18);} else {this.dismiss();}}}
