============问题描述============
public class Yao extends Activity implements SensorEventListener
{
EditText tv =(EditText)findViewById(R.id.editText1);
Button button =(Button)findViewById(R.id.button1);
SensorManager sensorManager = null;
Vibrator vibrator = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
button.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
tv.setText("初始文本");
}
});
sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
vibrator = (Vibrator) getSystemService(Service.VIBRATOR_SERVICE);
}
@Override
protected void onPause()
{
super.onPause();
sensorManager.unregisterListener(this);
}
@Override
protected void onResume()
{
super.onResume();
sensorManager.registerListener(this,
sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
SensorManager.SENSOR_DELAY_NORMAL);
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy)
{
//当传感器精度改变时回调该方法，Do nothing.
}
@Override
public void onSensorChanged(SensorEvent event)
{
int sensorType = event.sensor.getType();
//values[0]:X轴，values[1]：Y轴，values[2]：Z轴
float[] values = event.values;
if (sensorType == Sensor.TYPE_ACCELEROMETER)
{
if ((Math.abs(values[0]) > 17 || Math.abs(values[1]) > 17 || Math
.abs(values[2]) > 17))
{
// Log.d("sensor x ", "============ values[0] = " + values[0]);
// Log.d("sensor y ", "============ values[1] = " + values[1]);
// Log.d("sensor z ", "============ values[2] = " + values[2]);
tv.setText("摇一摇成功!!!");
//摇动手机后，再伴随震动提示~~
vibrator.vibrate(500);
}
}
}
