如何获取当前的屏幕方向？

Question

我只想在我的方向处于横向时设置一些标志,这样当在onCreate()中重新创建活动时,我可以在纵向和横向加载的内容之间切换.我已经有了一个处理我的布局的layout-land xml.

public void onConfigurationChanged(Configuration _newConfig) {

        if (_newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
            this.loadURLData = false;
        }

        if (_newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
            this.loadURLData = true;
        }

        super.onConfigurationChanged(_newConfig);
    }

覆盖onConfigurationChanged将阻止我的layout-land xml以横向方向加载.

我只想在onCreate()中获取设备的当前方向.我怎么能得到这个？

Answer 1

Activity.getResources().getConfiguration().orientation

Answer 2

int orientation = this.getResources().getConfiguration().orientation;
if (orientation == Configuration.ORIENTATION_PORTRAIT) {
    // code for portrait mode
} else {
    // code for landscape mode
}

当超类this是Context

Answer 3

在某些设备void onConfigurationChanged()可能会崩溃.用户将使用此代码获取当前屏幕方向.

public int getScreenOrientation()
{
    Display getOrient = getActivity().getWindowManager().getDefaultDisplay();
    int orientation = Configuration.ORIENTATION_UNDEFINED;
    if(getOrient.getWidth()==getOrient.getHeight()){
        orientation = Configuration.ORIENTATION_SQUARE;
    } else{ 
        if(getOrient.getWidth() < getOrient.getHeight()){
            orientation = Configuration.ORIENTATION_PORTRAIT;
        }else { 
             orientation = Configuration.ORIENTATION_LANDSCAPE;
        }
    }
    return orientation;
}

并使用

if (orientation==1)        // 1 for Configuration.ORIENTATION_PORTRAIT
{                          // 2 for Configuration.ORIENTATION_LANDSCAPE
   //your code             // 0 for Configuration.ORIENTATION_SQUARE
}

Answer 4

int rotation =  getWindowManager().getDefaultDisplay().getRotation();

这将给出正常和反向的所有方向

并像处理它一样

int angle = 0;
switch (rotation) {
    case Surface.ROTATION_90:
        angle = -90;
        break;
    case Surface.ROTATION_180:
        angle = 180;
        break;
    case Surface.ROTATION_270:
        angle = 90;
        break;
    default:
        angle = 0;
        break;
}

Answer 5

getActivity().getResources().getConfiguration().orientation

此命令为Portrait返回int值1,为Landscape返回2

Answer 6

如果有人想要获得有意义的方向描述(比如传递给onConfigurationChanged(..)那些reverseLandscape,sensorLandscape等等),只需使用即可getRequestedOrientation()
