Here is the way I did the same thing (my App was also in landscape). First I get the orientation values (analogical to the way you do): <pre><code>final float pi = (float) Math.PI; final float rad2deg = 180/pi; public static float x; //pitch public static float y; //roll public static float z; //azimuth float[] gravity = new float[3]; float[] geomag = new float[3]; float[] inOrientMatrix = new float[16]; float[] outOrientMatrix= new float[16]; float orientation[] = new float[3]; public static GLSurfaceView glView; // (...) public void onSensorChanged(SensorEvent event) { switch (event.sensor.getType()){ case Sensor.TYPE_ACCELEROMETER: gravity = event.values.clone(); break; case Sensor.TYPE_MAGNETIC_FIELD: geomag = event.values.clone(); break; } if (gravity != null && geomag != null){ if (SensorManager.getRotationMatrix(inOrientMatrix, null, gravity, geomag)){ SensorManager.remapCoordinateSystem(inOrientMatrix, SensorManager.AXIS_X, SensorManager.AXIS_Z, outOrientMatrix); SensorManager.getOrientation(outOrientMatrix, orientation); x = orientation[1]*rad2deg; //pitch y = orientation[0]*rad2deg; //azimuth z = orientation[2]*rad2deg; //roll glView.requestRender(); ｝ </code></pre> Then in my rendered, in the onDrawFrame(GL10 gl) I do: <pre><code> gl.glLoadIdentity(); GLU.gluLookAt(gl, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, -1.0f, 0.0f, 1.0f, 0.0f); gl.glRotatef(MainActivity.x, 1.0f, 0.0f, 0.0f); gl.glRotatef(MainActivity.y, 0.0f, 1.0f, 0.0f); gl.glRotatef(MainActivity.z, 0.0f, 0.0f, 1.0f); //in case you have transformation, eg. the position of the object, you can do them here //gl.Translatef(0.0f, 0.0f, -DISTANCE NORTH); //gl.Translatef(0.0f, DISTANCE EAST, 0.0f); gl.glPushMatrix(); //object draw </code></pre> In other words, I rotate the whole world around me. A better way would be to change the direction of the camera using glLookAt, with the eye positioned at (0,0,0) and (0,1,0) being the up vector, but I simply couldn't get my center_view x,y,z values correctly. Hope this helps...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
