Android acceleration sensor simulated shake effect-android learning Tour (66)
This article mainly introduces the simple usage of android acceleration sensors. It simulates shaking. If the acceleration speed in the three directions of x, y, and z exceeds 15, the Toast will pop up, of course, you can set more complex policies. For example, the Code for judging the interval is as follows:

Public class MainActivity extends Activity {private SensorManager sensorManager; private TextView textView; @ Override protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); sensorManager = (SensorManager) getSystemService (Context. SENSOR_SERVICE); Sensor sensor = sensorManager. getdefasensensor (Sensor. TYPE_ACCELEROMETER); sens OrManager. registerListener (sensorEventListener, sensor, SensorManager. SENSOR_DELAY_NORMAL);} private SensorEventListener sensorEventListener = new SensorEventListener () {@ Override public void onSensorChanged (SensorEvent sensorEvent) {float xValue = Math. abs (sensorEvent. values [0]); float yValue = Math. abs (sensorEvent. values [1]); float zvalue = Math. abs (sensorEvent. values [2]); if (xValue> 15 | yVal Ue> 15 | zvalue> 15) {Toast. makeText (MainActivity. this, shake, Toast. LENGTH_LONG ). show () ;}@ Override public void onAccuracyChanged (Sensor sensor, int I) {};@ Override protected void onDestroy () {if (sensorManager! = Null) {sensorManager. unregisterListener (sensorEventListener);} super. onDestroy () ;}@ Override public boolean onCreateOptionsMenu (Menu menu) {// Inflate the menu; this adds items to the action bar if it is present. getMenuInflater (). inflate (R. menu. menu_main, menu); return true;} @ Override public boolean onOptionsItemSelected (MenuItem item) {// Handle action bar item clicks here. the action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest. xml. int id = item. getItemId (); // noinspection SimplifiableIfStatement if (id = R. id. action_settings) {return true;} return super. onOptionsItemSelected (item );}}
