Android-Vibrator的使用
Android-Vibrator的使用
Android手机中的震动由Vibrator实现。设置震动事件,需要知道其震动的时间长短、震动的周期等。
在android中,震动的时间一毫秒计算(1/1000秒),所以如果设置的时间值太小,会感觉不出来。
通过调用Vibrator的vibrate(long[] pattern, int repeat)方法实现。
前一个参数为设置震动的效果的数组,第二个参数为 -1表示只震动一次,为0则震动会一直持续。
一个demo:
- package com.shao.vibrator;
- import android.app.Activity;
- import android.os.Bundle;
- import android.os.Vibrator;
- import android.widget.CompoundButton;
- import android.widget.Toast;
- import android.widget.CompoundButton.OnCheckedChangeListener;
- import android.widget.ToggleButton;
- public class VibratorActivity extends Activity {
- /** Called when the activity is first created. */
- private Vibrator vibrator;
- private ToggleButton tog1;
- private ToggleButton tog2;
- private ToggleButton tog3;
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- init();
- tog1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
- @Override
- public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
- // TODO Auto-generated method stub
- if(isChecked){
- //设置震动周期
- vibrator.vibrate(new long[]{1000,10,100,1000}, -1);
- showToast("OK");
- }else{
- //取消震动
- vibrator.cancel();
- showToast("CANCEL");
- }
- }
- });
- tog2.setOnCheckedChangeListener(new OnCheckedChangeListener() {
- @Override
- public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
- // TODO Auto-generated method stub
- if(isChecked){
- //设置震动周期
- vibrator.vibrate(new long[]{100,100,100,1000}, 0);
- showToast("OK");
- }else{
- //取消震动
- vibrator.cancel();
- showToast("CANCEL");
- }
- }
- });
- tog3.setOnCheckedChangeListener(new OnCheckedChangeListener() {
- @Override
- public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
- // TODO Auto-generated method stub
- if(isChecked){
- //设置震动周期
- vibrator.vibrate(new long[]{1000,50,1000,50,1000}, 0);
- showToast("OK");
- }else{
- //取消震动
- vibrator.cancel();
- showToast("CANCEL");
- }
- }
- });
- }
- private void init(){
- tog1= (ToggleButton) findViewById(R.id.tog1);
- tog2= (ToggleButton) findViewById(R.id.tog2);
- tog3= (ToggleButton) findViewById(R.id.tog3);
- vibrator = (Vibrator) this.getSystemService(VIBRATOR_SERVICE);
- }
- private void showToast(String msg){
- Toast.makeText(this, msg, 1).show();
- }
- }
