我认为这段代码可以在方向改变生效后工作

Display getOrient = getWindowManager().getDefaultDisplay();

int orientation = getOrient.getOrientation();

覆盖的活动。onConfigurationChanged(Configuration newConfig)函数，如果你想在调用setContentView之前得到关于新方向的通知，请使用newConfig,orientation。

还有一种方法:

public int getOrientation()
{
    if(getResources().getDisplayMetrics().widthPixels>getResources().getDisplayMetrics().heightPixels)
    { 
        Toast t = Toast.makeText(this,"LANDSCAPE",Toast.LENGTH_SHORT);
        t.show();
        return 1;
    }
    else
    {
        Toast t = Toast.makeText(this,"PORTRAIT",Toast.LENGTH_SHORT);
        t.show();
        return 2;
    }       
}

老帖子我知道。不管方向是什么或者被交换了等等。我设计了这个功能，用来将设备设置在正确的方向上，而不需要知道肖像和景观特征是如何在设备上组织的。

   private void initActivityScreenOrientPortrait()
    {
        // Avoid screen rotations (use the manifests android:screenOrientation setting)
        // Set this to nosensor or potrait

        // Set window fullscreen
        this.activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        DisplayMetrics metrics = new DisplayMetrics();
        this.activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

         // Test if it is VISUAL in portrait mode by simply checking it's size
        boolean bIsVisualPortrait = ( metrics.heightPixels >= metrics.widthPixels ); 

        if( !bIsVisualPortrait )
        { 
            // Swap the orientation to match the VISUAL portrait mode
            if( this.activity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT )
             { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); }
            else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT ); }
        }
        else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); }

    }

效果好极了!

有很多方法可以做到这一点，这段代码适合我

 if (this.getWindow().getWindowManager().getDefaultDisplay()
                .getOrientation() == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) {
             // portrait mode
} else if (this.getWindow().getWindowManager().getDefaultDisplay()
                .getOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
                      // landscape
        }

Android SDK可以很好地告诉你:

getResources().getConfiguration().orientation

在运行时检查屏幕方向。

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

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();

    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();        
    }
}
