I want my android application to be only run in portrait mode? How can I do that?
This question is related to
android
screen-orientation
In Android Manifest File, put attribute for your <activity>
that android:screenOrientation="portrait"
in the manifest:
<activity android:name=".activity.MainActivity"
android:screenOrientation="portrait"
tools:ignore="LockedOrientationActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
or : in the MainActivity
@SuppressLint("SourceLockedOrientationActivity")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
There are two ways,
android:screenOrientation="portrait"
for each Activity in Manifest Filethis.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
in each java file.I use
android:screenOrientation="nosensor"
It is helpful if you do not want to support up side down portrait mode.
Old post I know. In order to run your app always in portrait mode even when orientation may be or is swapped etc (for example on tablets) I designed this function that is used to set the device in the right orientation without the need to know how the portrait and landscape features are organised on the device.
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); }
}
Works like a charm!
NOTICE:
Change this.activity
by your activity or add it to the main activity and remove this.activity
;-)
