Android中自定义PopupWindow实现弹出框并带有动画效果

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

<?xml version="1.0" encoding="utf-8"?>

</linearlayout>
动画r.style.animationpreview
<style name="animationpreview">
<item name="android:windowenteranimation">@anim/fade_in</item>
<item name="android:windowexitanimation">@anim/fade_out</item>
</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:toxscale="1.0"

@anim/fade_out
<!-- 左上角缩小 -->
<scale xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromxscale="1.0"
android:toxscale="0.001"
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;
}
}
});
