Android 13 设置界面会判断当前屏幕的大小,如果是大屏,则为双栏显示!

/** Whether to support embedding activity feature. */
public static boolean isEmbeddingActivityEnabled(Context context) {//update textfinal boolean isFlagEnabled = false;//FeatureFlagUtils.isEnabled(context,FeatureFlagUtils.SETTINGS_SUPPORT_LARGE_SCREEN);final boolean isSplitSupported = SplitController.getInstance().isSplitSupported();Log.d(TAG, "isFlagEnabled = " + isFlagEnabled);Log.d(TAG, "isSplitSupported = " + isSplitSupported);return isFlagEnabled && isSplitSupported;
}//当isFlagEnabled和isSplitSupported都为true时为双栏显示,反之则单栏,&&表示可以只修改其中一个为false就ok了
