How to show an Activity as pop-up on other Activity?
提问by bhups
I have an Activity A, and there is a button B in the view. If somebody presses B then I want a pop-up which can take some part of screen making the A invisible in that area but rest of A is visible but not active. How can I achieve this?
我有一个活动 A，视图中有一个按钮 B。如果有人按下 B 那么我想要一个弹出窗口，它可以占据屏幕的一部分，使 A 在该区域不可见，但 A 的其余部分可见但不活动。我怎样才能做到这一点？

If you want to do this using an Activity instead of a Dialog, you can do this by setting the activity's theme to android:theme="@android:style/Theme.Dialog"in the manifest - this will make the activity appear like a dialog (floating on top of whatever was underneath it).
如果您想使用 Activity 而不是 Dialog 来执行此操作，您可以通过android:theme="@android:style/Theme.Dialog"在清单中将 Activity 的主题设置为 来执行此操作- 这将使 Activity 看起来像一个对话框（浮动在其下方的任何内容之上）。

Just to add on oli's answer, make sure to use the Dialog from the theme you are using in your application.
In my case I did android:theme="@android:style/Theme.Holo.Light.Dialog"
只是为了添加 oli 的答案，请确保使用您在应用程序中使用的主题中的 Dialog。
就我而言，我做到了android:theme="@android:style/Theme.Holo.Light.Dialog"

Setting theme to android:theme="@android:style/android:Theme.Holo.Panel"worked for me.
设置主题android:theme="@android:style/android:Theme.Holo.Panel"为我工作。
Steps -
1. Set theme for the activity in manifest file to android:theme="@android:style/android:Theme.Holo.Panel"(This has to be changed to whatever theme is being used). Ex:
步骤 - 1. 将清单文件中活动的主题设置为android:theme="@android:style/android:Theme.Holo.Panel"（必须将其更改为正在使用的任何主题）。前任：
<activity
android:name=".EditActivity"
android:theme="@android:style/android:Theme.Holo.Panel"
android:label="@string/title_activity_edit" >
</activity>
- In the activity resource xml set appropriate padding and width on the root layout. I have set it to
0and added a child layout at the beginning with alpha to show some part of the previous activity.
- 在活动资源 xml 中，在根布局上设置适当的填充和宽度。我已将其设置为
0并在开头添加了一个带有 alpha 的子布局以显示先前活动的某些部分。

You can do it programicly
您可以通过编程方式进行
Create Class MyDialog
创建类 MyDialog
import android.app.Activity;
import android.app.Dialog;
import android.view.Window;
import android.widget.TextView;
public class MyDialoge{
Activity activity;
TextView txt_Message;
Dialog dialog;
public ViewDialog(Activity activity) {
this.activity = activity;
}
public void showDialog(String message){
dialog = new Dialog(activity);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.custom_progress_dialog);
txt_Message = dialog.findViewById(R.id.txt_message);
txt_Message.setText(message);
//if you want to dimiss the dialog
//dialog.dimiss()
dialog.show();
}
public void dimiss(){
try {
dialog.dismiss();
} catch (Exception e) {
e.printStackTrace();
}
}
}
After that crate the layout -> call it my_dialog
然后将布局打包-> 将其称为 my_dialog
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_gravity="center"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Hello PopUp Message"/>
</RelativeLayout>
In your Activity
在您的活动中
MyDialog myDialog = new MyDialog(MainActivity.this);
myDialog.showDialog("Say Hello to Me");
To dimiss
关闭
myDialog.dimiss();
