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View
this.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() {
@Override
public void onClick(View arg0) {
LostPopupWindow.this.dismiss();
lost.onLost(2);
}
});
mySend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
LostPopupWindow.this.dismiss();
lost.onLost(1);
}
});
all.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
LostPopupWindow.this.dismiss();
lost.onLost(0);
}
});
}
/**

public void showPopupWindow(View parent) {
if (!this.isShowing()) {
