Android的弹窗效果有很多种，就最简单而言，就可以调用一个AlertDialog弹窗显示，可是要自定义弹窗效果有以下这种方法，就我个人而言感觉挺方便的，适用性也挺广的。
首先先简单写个AlertDialog的使用
public void showDialog(){
AlertDialog dialog = new AlertDialog.Builder(this)
.setTitle("提示")
.setMessage(getResources().getString("你确定退出吗?")
.setPositiveButton("取消", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
}).setNegativeButton("确定", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
}).create();
dialog.show();
}
}
接下来就是自定义弹窗效果图：
下面是示例代码：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:id="@+id/top"
>
<TextView android:layout_width="match_parent"
android:layout_height="40.5dip"
android:text="@string/select_head"
android:layout_marginLeft="7.2dip"
android:layout_marginRight="7.2dip"
android:gravity="center"
android:textColor="#aaaaaa"
/>
<Button
android:id="@+id/takephoto"
android:layout_width="match_parent"
android:layout_height="40.5dip"
android:layout_marginLeft="7.2dip"
android:layout_marginRight="7.2dip"
android:text="@string/takephoto"
android:background="@null"
android:textColor="#fc4643"
/>
<Button
android:id="@+id/selectfromalbum"
android:layout_width="match_parent"
android:layout_height="40.5dip"
android:layout_marginLeft="7.2dip"
android:layout_marginRight="7.2dip"
android:text="@string/takefromalbum"
android:background="@null"
android:textColor="#fc4643"
/>
<Button
android:id="@+id/cancel"
android:layout_width="match_parent"
android:layout_height="40.5dip"
android:layout_marginLeft="7.2dip"
android:layout_marginRight="7.2dip"
android:layout_marginTop="7.2dip"
android:text="@string/cancel"
android:background="@null"
android:textColor="#fc4643"
/>
</LinearLayout>
</RelativeLayout>
public class SelectPopupWindow extends PopupWindow {
Button takePhoto;

View menuView;
public SelectPopupWindow(Context ctx, OnClickListener onClickListener) {
LayoutInflater inflater = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
menuView = inflater.inflate(R.layout.modify_head, null); //可以采用各种样式，自定义view

setFocusable(true); //弹出窗体后可点击
//setAnimationStyle(R.style.AnimBottom); //设置动画
menuView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int height = menuView.findViewById(R.id.top).getTop();
Log.e("huang", " top height:"+height+" y:"+event.getY());
int y = (int) event.getY();
if(y<height){
dismiss();
}
return true;
}
});
}
}
