Android Activity 作为对话框

Android Activity as a dialog

提问by d-man

I have an Activity named whereActitywhich has child dialogs as well. Now, I want to display this activity as a dialog for another activity.

我有一个名为 Activity 的活动whereActity，它也有子对话框。现在，我想将此活动显示为另一个活动的对话框。

How can I do that?

我怎样才能做到这一点？

回答by d-man

To start activity as dialog I defined it like this in AndroidManifest.xml:

要将活动作为对话框开始，我在以下定义了它AndroidManifest.xml：

<activity android:theme="@android:style/Theme.Dialog" />

Use this property inside your activitytag to avoid that your Dialog appears in the recently used apps list

在activity标签内使用此属性可避免您的 Dialog 出现在最近使用的应用程序列表中

android:excludeFromRecents="true"

If you want to stop your dialog / activity from being destroyed when the user clicks outside of the dialog:

如果您想在用户单击对话框外时阻止您的对话框/活动被破坏：

After setContentView()in your Activityuse:

之后setContentView()在您的Activity使用：

this.setFinishOnTouchOutside(false);

this.setFinishOnTouchOutside(false);

Now when I call startActivity()it displays as a dialog, with the previous activity shown when the user presses the back button.

现在，当我调用startActivity()它时，它显示为一个对话框，当用户按下后退按钮时会显示上一个活动。

Note that if you are using ActionBarActivity(or AppCompat theme), you'll need to use @style/Theme.AppCompat.Dialoginstead.

请注意，如果您正在使用ActionBarActivity（或 AppCompat 主题），则需要@style/Theme.AppCompat.Dialog改用。

Use this code so that the dialog activity won't be closed when the user touches outside the dialog box:

使用此代码，以便在用户触摸对话框外时不会关闭对话框活动：

this.setFinishOnTouchOutside(false);

You can define this style in values/styles.xml to perform a more former Splash :

您可以在 values/styles.xml 中定义此样式以执行更旧的 Splash ：

   <style name="Theme.UserDialog" parent="android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:background">@android:color/transparent</item>
        <item name="android:windowBackground">@drawable/trans</item>
    </style>

And use it AndroidManifest.xml:

并使用它 AndroidManifest.xml：

   <activity android:name=".SplashActivity"
          android:configChanges="orientation"
          android:screenOrientation="sensor"
          android:theme="@style/Theme.UserDialog">

1 - You can use the same activity as both dialog and full screen, dynamically:

1 - 您可以动态地使用与对话框和全屏相同的活动：

Call setTheme(android.R.style.Theme_Dialog)before calling setContentView(...)and super.oncreate()in your Activity.

呼叫setTheme(android.R.style.Theme_Dialog)调用之前setContentView(...)和super.oncreate()你的活动。

2 - If you don't plan to change the activity theme style you can use

2 - 如果您不打算更改您可以使用的活动主题样式

<activity android:theme="@android:style/Theme.Dialog" />

(as mentioned by @faisal khan)

回答by aaronsnoswell

If your activity is being rendered as a dialog, simply add a button to your activity's xml,

如果您的活动被呈现为对话框，只需在您的活动的 xml 中添加一个按钮，

<Button
    android:id="@+id/close_button"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Dismiss" />

Then attach a click listener in your Activity's Java code. In the listener, simply call finish()

然后在您的 Activity 的 Java 代码中附加一个单击侦听器。在侦听器中，只需调用finish()

Button close_button = (Button) findViewById(R.id.close_button);
close_button.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        finish();
    }
});

That should dismiss your dialog, returning you to the calling activity.

这应该会关闭您的对话，让您返回到调用活动。

If you want to remove activity header & provide a custom view for the dialog add the following to the activity block of you manifest

如果要删除活动标题并为对话框提供自定义视图，请将以下内容添加到清单的活动块中

android:theme="@style/Base.Theme.AppCompat.Dialog"

and design your activity_layout with your desired view

并使用您想要的视图设计您的活动布局

回答by Gyan Swaroop Awasthi

Set the theme in your android manifest file.

在您的 android 清单文件中设置主题。

<activity android:name=".LoginActivity"
            android:theme="@android:style/Theme.Dialog"/>

And set the dialog state on touch to finish.

并在触摸时设置对话框状态以完成。

this.setFinishOnTouchOutside(false);
