    <p>I m trying to make an app that would show me at what angle my device is being rotate and also have a menu that would provide me option to see the result in degree or radian but after running this code only screen is being appeared showing the layout and on rotating the device nothing is happening plzz tell me where i m wrong Thanx in advance</p> <pre><code>package com.example.directordetector; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mInitialized = false; mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); mAccelerometer = mSensorManager .getDefaultSensor(Sensor.TYPE_LINEAR_ACCELERATION); mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL); } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.menu_name, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.degree: m = 0; return true; case R.id.radian: m = 1; return true; default: return super.onOptionsItemSelected(item); } } protected void onResume() { super.onResume(); mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL); } protected void onPause() { super.onPause(); mSensorManager.unregisterListener(this); } @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { // TODO Auto-generated method stub } @Override public void onSensorChanged(SensorEvent event) { // TODO Auto-generated method stub TextView tvX = (TextView) findViewById(R.id.x_axis); TextView tvY = (TextView) findViewById(R.id.y_axis); TextView tvZ = (TextView) findViewById(R.id.z_axis); float x = event.values[0]; float y = event.values[1]; float z = event.values[2]; if (!mInitialized) { mLastX = x; mLastY = y; mLastZ = z; tvX.setText("0.0"); tvY.setText("0.0"); tvZ.setText("0.0"); mInitialized = true; } else { float deltaX = Math.abs(mLastX - x); float deltaY = Math.abs(mLastY - y); float deltaZ = Math.abs(mLastZ - z); if (deltaX &lt; NOISE) deltaX = (float) 0.0; if (deltaY &lt; NOISE) deltaY = (float) 0.0; if (deltaZ &lt; NOISE) deltaZ = (float) 0.0; mLastX = x; mLastY = y; mLastZ = z; if (m == 1) { deltaX = (float) (deltaX * (3.18 / 180)); deltaX = (float) (deltaX * (3.18 / 180)); deltaX = (float) (deltaX * (3.18 / 180)); } tvX.setText(Float.toString(deltaX)); tvY.setText(Float.toString(deltaY)); tvZ.setText(Float.toString(deltaZ)); } } } </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
