Android中自定义PopupWindow实现弹出框并带有动画效果_Android

使用PopupWindow来实现弹出框，并且带有动画效果

首先自定义PopupWindow

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);
}
});
}
/**
* 显示popupWindow
*
* @param parent
*/
public void showPopupWindow(View parent) {
if (!this.isShowing()) {
// 以下拉方式显示popupwindow
this.showAsDropDown(parent, parent.getLayoutParams().width / 2, 18);
} else {
this.dismiss();
}
}
}

R.layout.lost_pop_menu文件

动画R.style.AnimationPreview

</style>
@anim/fade_in
<?xml version="1.0" encoding="utf-8"?>
<!-- 左上角扩大-->
<scale xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromXScale="0.001"
android:toXScale="1.0"

android:pivotY="10%"
android:duration="200" />
@anim/fade_out
<!-- 左上角缩小 -->
<scale xmlns:android="http://schemas.android.com/apk/res/android"

android:fromYScale="1.0"
android:toYScale="0.001"
android:pivotX="100%"
android:pivotY="10%"
android:duration="200" />

接下来就是使用了

LostPopupWindow popWindow = new LostPopupWindow(ZiXunDetailActivity.this);
((ImageView)(popWindow.getConentView().findViewById(R.id.img5))).setImageResource(R.drawable.ckplico);
((ImageView)(popWindow.getConentView().findViewById(R.id.img6))).setImageResource(R.drawable.fbplico);
((ImageView)(popWindow.getConentView().findViewById(R.id.img7))).setImageResource(R.drawable.zfplico);
((TextView)(popWindow.getConentView().findViewById(R.id.item_content))).setText("查看评论");
((TextView)(popWindow.getConentView().findViewById(R.id.item_content1))).setText("发表评论");
((TextView)(popWindow.getConentView().findViewById(R.id.item_content2))).setText("转发文章");
popWindow.showPopupWindow(linMain);
popWindow.onLost(new Lost() {
@Override
public void onLost(int index) {
switch (index){
case 0: //转发文章
break;
case 1: //发表评论
lineFooter.setVisibility(View.VISIBLE);
break;
case 2://查看评论
Bundle bundle=new Bundle();
bundle.putString("id",mID);
startActivity(PingLunActivity.class, "热门评论", bundle);
break;
}
}
});
