[android-developers] Re: how can i check landscap orientation ?
Hi
make use of sensorListener and it will work . i have used the same
.. when u use sensorlistener and sensormanager in ur view it has got
an override method as onSizeChanged which return the width and
height. so using change in size u will get the orientation
Below is a code for u of orientation check . enjoy :
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.hardware.SensorManager;
import android.hardware.SensorListener;
import android.util.Log;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Path;
import android.graphics.RectF;
public class Midlet extends Activity {
/** Tag string for our debug logs */
private static final String TAG = Sensors;
private SensorManager mSensorManager;
private GraphView mGraphView;
private class GraphView extends View implements SensorListener
{
public GraphView(Context context) {
super(context);
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
System.out.println(on sizechanged);
super.onSizeChanged(w, h, oldw, oldh);
}
@Override
protected void onDraw(Canvas canvas) {
}
public void onSensorChanged(int sensor, float[] values) {
}
public void onAccuracyChanged(int sensor, int accuracy) {
// TODO Auto-generated method stub
}
}
/**
* Initialization of the Activity after it is first created. Must at
least
* call {...@link android.app.Activity#setContentView setContentView()} to
* describe what is to be displayed in the screen.
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
// Be sure to call the super class.
super.onCreate(savedInstanceState);
mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
mGraphView = new GraphView(this);
setContentView(mGraphView);
}
@Override
protected void onResume() {
super.onResume();
mSensorManager.registerListener(mGraphView,
SensorManager.SENSOR_ACCELEROMETER |
SensorManager.SENSOR_MAGNETIC_FIELD |
SensorManager.SENSOR_ORIENTATION,
SensorManager.SENSOR_DELAY_FASTEST);
}
@Override
protected void onStop() {
mSensorManager.unregisterListener(mGraphView);
super.onStop();
}
}

Hi
Many thanks for replies. I actually want to do
something if the screen orientation is landscap. Am trying something
like this...
if(getRequestedOrientation()== landscap)
{
{
But it was not working. So if the way is correct then please tell
me
if(getRequestedOrientation()== )
Or suggest something another way.
Thanks in advance.

[android-developers] Re: how can i check landscap orientation ?
If you just want to find the current orientation of the screen, the sensor
manager is just totally the wrong direction to take.
What you want to do is use getResources().getConfiguration() (sorry I
incorrectly previously posted to use getDisplayMetrics()).
You can follow the docs on getRequestedOrientation() to see the (fairly
large) set of possible values it returns and that usually it is not telling
you the actual current orientation:
http://developer.android.com/reference/android/app/Activity.html#getRequestedOrientation()
http://developer.android.com/reference/android/content/pm/ActivityInfo.html#screenOrientation
http://developer.android.com/reference/android/R.attr.html#screenOrientation
So if you are getting SCREEN_ORIENTATION_PORTRAIT or
SCREEN_ORIENTATION_LANDSCAPE from here, you are just finding out that you
had told the system that you want to force the screen to be portrait or
landscape while your activity is in the foreground.
This is what you want to use if you just want to find out the current screen
orientation:
http://developer.android.com/reference/android/content/res/Resources.html#getConfiguration()
http://developer.android.com/reference/android/content/res/Configuration.html#orientation

[android-developers] Re: how can i check landscap orientation ?
Pls add andoid:configChanges=orientation|keyboard
And override onConfigurationChanged and check the orientation against
Configuration.ORIENTATION_LANDSCAPE or potrait
