利用Sensor兑现android手机类似于微信摇一摇

利用Sensor实现android手机类似于微信摇一摇

传感器有几种类型：
方向传感器： Sensor.TYPE_ORIENTATION
加速度(重力)传感器： Sensor.TYPE_ACCELEROMETER
光线传感器: Sensor.TYPE_LIGHT
磁场传感器： Sensor.TYPE_MAGNETIC_FIELD
距离(临近性)传感器： Sensor.TYPE_PROXIMITY
温度传感器： Sensor.TYPE_TEMPERATURE

这里我们利用的是加速度传感器

package com.jamin.sensor;import android.app.Activity;import android.app.Service;import android.hardware.Sensor;import android.hardware.SensorEvent;import android.hardware.SensorEventListener;import android.hardware.SensorManager;import android.os.Bundle;import android.os.Vibrator;import android.util.Log;import android.view.View;import android.widget.Button;import android.widget.TextView;public class SensorTestActivity extends Activity implements SensorEventListener{	/** Called when the activity is first created. */	TextView tv = null;	Button button = null;	SensorManager sensorManager = null;	Vibrator vibrator = null;	@Override	public void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.main);		button = (Button) findViewById(R.id.button1);		tv = (TextView) findViewById(R.id.textview1);		button.setOnClickListener(new View.OnClickListener() {			@Override			public void onClick(View v) {				// TODO Auto-generated method stub				tv.setText("文本复原");				}		});		sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);		vibrator = (Vibrator) getSystemService(Service.VIBRATOR_SERVICE);	}	@Override	protected void onPause() {		// TODO Auto-generated method stub		super.onPause();		sensorManager.unregisterListener(this);	}	@Override	protected void onResume() {		// TODO Auto-generated method stub		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 ", "============ values[0] = " + values[0]);				Log.d("sensor ", "============ values[1] = " + values[1]);				Log.d("sensor ", "============ values[2] = " + values[2]);				tv.setText("摇一摇");				//摇动手机后，再伴随震动提示~~				vibrator.vibrate(500);			}		}	}}

?记得在onresume和onpause的时候开关sensor的监听事件。

如果想调整sensor的敏感程度，就去修改，value[0,1,2] 大于的上限。
