我有一个简单的hello world Android测试项目.在我的AndroidManifest.xml中,我已经设置好了
android:screenOrientation="portrait"
android:configChanges="keyboardHidden|keyboard|orientation">

但是当我调试我的代码时,变量isLandscape是真的,它应该是假的
boolean isLandscape = getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE;

我知道我也可以通过代码设置活动方向,但出于某些原因我需要在xml中设置它.我该怎么做?
编辑:我的AndroidManifest.xml

我的实际onCreate活动方法:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
boolean isLandscape = getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE;
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
int frameBufferWidth = isLandscape ? 480 : 320;
int frameBufferHeight = isLandscape ? 320 : 480;
Bitmap frameBuffer = Bitmap.createBitmap(frameBufferWidth,
frameBufferHeight, Config.RGB_565);
float scaleX = (float) frameBufferWidth
/ getWindowManager().getDefaultDisplay().getWidth();
float scaleY = (float) frameBufferHeight
/ getWindowManager().getDefaultDisplay().getHeight();
renderView = new AndroidFastRenderView(this, frameBuffer);
graphics = new AndroidGraphics(getAssets(), frameBuffer);
fileIO = new AndroidFileIO(getAssets());
audio = new AndroidAudio(this);
input = new AndroidInput(this, renderView, scaleX, scaleY);
screen = this.getStartScreen();
setContentView(renderView);
PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "GLGame");
}

现在它越来越奇怪了,isLandscape变量是True,但有时它是False.它有点像一个bug.

确保将其放在<activity>标签中,而不是<application>标签中.
它仅适用于<activity>标签,但如果将其放入<application>标签中则不会抱怨.

你需要把它放在Activity你定义的每一个中manifest.xml
