问题描述

每当我尝试在应用程序中将方向更改为横向时，我正在开发的应用程序就会崩溃.

Whenever I try to change the the orientation to landscape in the app I'm developing it crashes.

用于纵向模式 RES/布局/activity_main.xml 用于风景模式 res/layout-land/activity_main.xml

for portrait mode res/layout/activity_main.xml for landscape mode res/layout-land/activity_main.xml

我正在使用Linear-Layout，但是日食显示此LinearLayout布局或其LinearLayout父级是无用的".下面是风景模式的代码.请帮忙.

推荐答案

在您的活动清单中使用:

use in your Manifest at your activity:

android:configChanges="orientation"

然后尝试使用:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    Display display = ((WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
    AddArticleActivity.DISPLAYROTATION = display.getRotation();
    if (youractivity.DISPLAYROTATION == Surface.ROTATION_90 || youractivity.DISPLAYROTATION == Surface.ROTATION_270) {
        do LANDSCAPE;
    } else {
        do PORTRAIT;
    }

}
