防止在方向改变时重新启动活动 [英] prevent activity restarting when orientation changes

问题描述

我是 android 开发的新手.我有单独的纵向和横向模式屏幕.当我改变我的方向时，相应的屏幕被加载并且活动重新启动.现在我不希望我的活动在我改变方向时重新启动，但应该加载其相应的屏幕(axml).

I am new to android development .I have separate screens for portrait and landscape mode.When i change my orientation corresponding screen gets loaded and activity restarts . Now i do not want my activity to restart when i change the orientation but should load its corresponding screen(axml).

我试过了

[活动(标签 ="MyActivity",ConfigurationChanges=Android.Content.PM.ConfigChanges.Orientation)]

[Activity (Label = "MyActivity",ConfigurationChanges=Android.Content.PM.ConfigChanges.Orientation)]

上述行停止重新启动活动，但它加载了相同的屏幕(axml).请建议.谢谢

the above line stops activity getting restarted but it loads the same screen(axml). Please suggest . thanks

推荐答案

将此代码写入您的活动

Write this code in your activity

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
        setContentView(R.layout.landscapeView);

    } else {
        setContentView(R.layout.portraitView);
    }
}

并在您的清单文件中添加这一行

And also add this line in your Manifest file

android:configChanges="orientation|keyboardHidden|screenSize"

所以这将处理这两件事，它不会重新启动您的活动，而是会根据您的方向更改加载布局.

So this will handle both things, it will not restart your activity and will load the layout as per your orientation changes.
