我的 Android 项目有问题。我正在为手机和平板电脑创建不同的布局,但有一些问题。这些布局使用不同的片段。这是我的 MainActivity onCreate 方法:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
if (isTablet(this.getApplicationContext()) &&
getResources().getConfiguration().orientation
== Configuration.ORIENTATION_LANDSCAPE){
mNavigationFragment = (NavigationFragment)
getSupportFragmentManager().findFragmentById(R.id.navigation);
} else {
mNavigationDrawerFragment = (NavigationDrawerFragment)
getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
}
mTitle = getTitle();
getSupportFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
@Override
public void onBackStackChanged() {
Fragment f = getSupportFragmentManager().findFragmentById(R.id.container);
if (f != null){
updateTitleAndDrawer (f);
}
}
});
}
这是 isTablet 方法:
public static boolean isTablet(Context context) {
return (context.getResources().getConfiguration().screenLayout
& Configuration.SCREENLAYOUT_SIZE_MASK)
>= Configuration.SCREENLAYOUT_SIZE_LARGE;
}
但关键是,当我改变方向时,布局不会改变。你能告诉一些建议吗?
忘了提,我在 AndroidManifest 中有以下行
android:configChanges="keyboardHidden|orientation|screenSize">
