Android中振动器(Vibrator)的使用

系统获取Vibrator也是调用Context的getSystemService方法,接下来就可以调用Vibrator的方法控制手机振动了。Vibrator只有三个方法控制手机振动:

1、vibrate(long milliseconds):控制手机振动的毫秒数。

2、vibrate(long[] pattern,int repeat):指定手机以pattern模式振动,例如指定pattern为new long[]{400,800,1200,1600},就是指定在400ms、800ms、1200ms、1600ms这些时间点交替启动、关闭手机振动器,其中repeat指定pattern数组的索引,指定pattern数组中从repeat索引开始的振动进行循环。-1表示只振动一次,非-1表示从pattern的指定下标开始重复振动。

3、cancel():关闭手机振动

下面通过一个示例来演示Vibrator的使用:

Activity:

package com.guyun.vibratortest;



import android.app.Activity;

import android.os.Bundle;

import android.os.Vibrator;

import android.widget.CompoundButton;

import android.widget.CompoundButton.OnCheckedChangeListener;

import android.widget.ToggleButton;



public class VibratorTestActivity extends Activity implements

		OnCheckedChangeListener {

	private Vibrator vibrator;

	private ToggleButton tog1;

	private ToggleButton tog2;

	private ToggleButton tog3;

	private ToggleButton tog4;



	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.activity_vibrator_test);

		// 获取系统的Vibrator服务

		vibrator = (Vibrator) this.getSystemService(VIBRATOR_SERVICE);

		tog1 = (ToggleButton) findViewById(R.id.activity_vibrator_test_tb1);

		tog2 = (ToggleButton) findViewById(R.id.activity_vibrator_test_tb2);

		tog3 = (ToggleButton) findViewById(R.id.activity_vibrator_test_tb3);

		tog4 = (ToggleButton) findViewById(R.id.activity_vibrator_test_tb4);

		tog1.setOnCheckedChangeListener(this);

		tog2.setOnCheckedChangeListener(this);

		tog3.setOnCheckedChangeListener(this);

		tog4.setOnCheckedChangeListener(this);



	}



	@Override

	public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

		if (isChecked) {

			if (buttonView == tog1) {

				// 设置震动周期

				vibrator.vibrate(new long[] { 1000, 10, 100, 1000 }, -1);

			} else if (buttonView == tog2) {

				vibrator.vibrate(new long[] { 100, 100, 100, 1000 }, 0);

			} else if (buttonView == tog3) {

				vibrator.vibrate(new long[] { 1000, 50, 1000, 50, 1000 }, 0);

			} else if (buttonView == tog4) {

				// 设置震动时长

				vibrator.vibrate(5000);

			}

		} else {

			// 关闭震动

			vibrator.cancel();

		}



	}

}
