I just want to set some flags when my orientation is in landscape so that when the activity is recreated in onCreate() i can toggle between what to load in portrait vs. landscape. I already have a layout-land xml that is handling my layout.
public void onConfigurationChanged(Configuration _newConfig) {
if (_newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
this.loadURLData = false;
}
if (_newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
this.loadURLData = true;
}
super.onConfigurationChanged(_newConfig);
}
Over-riding onConfigurationChanged will prevent my layout-land xml from loading in landscape orientation.
I just want to get the current orientation of my device in onCreate(). How can I get this?
This question is related to
java
android
configuration
orientation
int orientation = this.getResources().getConfiguration().orientation;
if (orientation == Configuration.ORIENTATION_PORTRAIT) {
// code for portrait mode
} else {
// code for landscape mode
}
When the superclass of this
is Context
if you want to override that onConfigurationChanged method and still want it to do the basic stuff then consider using super.onConfigyrationChanged() as the first statement in the overriden method.
int rotation = getWindowManager().getDefaultDisplay().getRotation();
this will gives all orientation like normal and reverse
and handle it like
int angle = 0;
switch (rotation) {
case Surface.ROTATION_90:
angle = -90;
break;
case Surface.ROTATION_180:
angle = 180;
break;
case Surface.ROTATION_270:
angle = 90;
break;
default:
angle = 0;
break;
}
In your activity class use the method below :
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
setlogo();// Your Method
Log.d("Daiya", "ORIENTATION_LANDSCAPE");
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
setlogoForLandScape();// Your Method
Log.d("Daiya", "ORIENTATION_PORTRAIT");
}
}
Then to declare that your activity handles a configuration change, edit the appropriate element in your manifest file to include the android:configChanges
attribute with a value that represents the configuration you want to handle. Possible values are listed in the documentation for the android:configChanges
attribute (the most commonly used values are "orientation" to prevent restarts when the screen orientation changes and "keyboardHidden" to prevent restarts when the keyboard availability changes). You can declare multiple configuration values in the attribute by separating them with a pipe | character.
<activity android:name=".MyActivity"
android:configChanges="orientation|keyboardHidden"
android:label="@string/app_name">
That's all!!
I just want to propose another alternative that will concern some of you :
android:configChanges="orientation|keyboardHidden"
implies that we explicitly declare the layout to be injected.
In case we want to keep the automatic injection thanks to the layout-land and layout folders. All you have to do is add it to the onCreate:
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
getSupportActionBar().hide();
} else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
getSupportActionBar().show();
}
Here, we display or not the actionbar depending on the orientation of the phone
In some devices void onConfigurationChanged()
may crash. User will use this code to get current screen orientation.
public int getScreenOrientation()
{
Display getOrient = getActivity().getWindowManager().getDefaultDisplay();
int orientation = Configuration.ORIENTATION_UNDEFINED;
if(getOrient.getWidth()==getOrient.getHeight()){
orientation = Configuration.ORIENTATION_SQUARE;
} else{
if(getOrient.getWidth() < getOrient.getHeight()){
orientation = Configuration.ORIENTATION_PORTRAIT;
}else {
orientation = Configuration.ORIENTATION_LANDSCAPE;
}
}
return orientation;
}
And use
if (orientation==1) // 1 for Configuration.ORIENTATION_PORTRAIT
{ // 2 for Configuration.ORIENTATION_LANDSCAPE
//your code // 0 for Configuration.ORIENTATION_SQUARE
}
In case anyone would like to obtain meaningful orientation description (like that passed to onConfigurationChanged(..)
with those reverseLandscape
, sensorLandscape
and so on), simply use getRequestedOrientation()
getActivity().getResources().getConfiguration().orientation
this command returns int value 1 for Portrait and 2 for Landscape
