Question

我的应用程序中有一个非常奇妙的问题。我的活动中有一个文本视图，该文本视图是从sqlite获取的文本，如下所示：

Hello

World!

但是当我第一次启动我的应用程序时，我的文本视图会显示如下文本：

Hello word!

当我离开应用程序并清除我的应用程序RAM内存，然后返回到应用程序时，我的文本视图会像下面这样正确显示文本：

Hello

World!

实际上，当第一次运行onCreate方法时，我的文本视图文本以单行显示。我尝试了类似使用recreate方法的方法：

public void recreate() {
    this.recreate();
}

在onCreate方法中：

recreate();

但是我的应用程序崩溃了！有办法解决这个问题吗？谢谢
