如何在不删除先前活动的情况下在另一个活动上显示透明活动?

How to display transparent activity on the another activity without removing previous activity ?

我能够创建透明活动，但是当我尝试使用intent推送它时，先前的活动将被删除.我希望我的透明活动位于上一个活动的顶部.

I am able to create transparent activity but when i trying to push it using intent , the previous activity gets removed. I want my transparent activity on the top of previous activity.

谢谢！

推荐答案

在清单中声明您的活动

 <activity android:name=".yourActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"/>

并为您的布局添加透明背景 像这样

and add a transperent background to your layout like this

 <?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
  android:background = "any tranparent image name"  >
 </RelativeLayout>

我认为您正在使用它来打开透明活动，从而完成上一个活动

i think you are using this to open your transparent activity it finish your previous activity

Intent intent =new Intent(mContext,yourNewActivity.class);
startActivity(intent);
finish();

从此处删除完成，然后将您的新活动移到之前的活动顶部

remove finish from here then your new activity in on top of previous activity like this

 Intent intent =new Intent(mContext,yourNewActivity.class);
 startActivity(intent);
