问题描述

先生我在android和一个文本字段中创建了一个按钮。当我单击按钮时，文本字段中的文本创建到按钮但是当我重新启动模拟器或应用程序时，更改不起作用，它显示第一个原始文本。例如按钮的第一个文本是第一个，当我单击按钮，文本通过文本字段更改为second.so当我重新启动模拟器或应用程序时，它首先显示文本而不是第二个。所以请给出一个简单的示例，用代码创建在android中永久更改。

        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="50dp"
        android:layout_marginTop="23dp"
        android:ems="10" >

        <requestfocus />
    </edittext>

    <Button

        android:id="@+id/button11"

推荐答案

您无法永久更改它。代码是代码。如果您需要不同的文本，则需要通过实施更改来重建应用程序。

You cannot change it permanently. The code is the code. If you want different text then you need to rebuild the app with the change implemented.
