Android手機中的震動由Vibrator實現。設置震動事件,需要知道其震動的時間長短、震動的周期等。
在android中,震動的時間一毫秒計算(1/1000秒),所以如果設置的時間值太小,會感覺不出來。
通過調用Vibrator的vibrate(long[] pattern, int repeat)方法實現。
前一個參數為設置震動的效果的數組,第二個參數為 -1表示只震動一次,為0則震動會一直持續。
一個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){
- //設置震動周期
- vibrator.vibrate(new long[]{1000,10,100,1000}, -1);
- showToast("OK");
- }else{
- //取消震動
- vibrator.cancel();
- showToast("CANCEL");
- }
- }
- });
- tog2.setOnCheckedChangeListener(new OnCheckedChangeListener() {
-
- @Override
- public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
- // TODO Auto-generated method stub
- if(isChecked){
- //設置震動周期
- vibrator.vibrate(new long[]{100,100,100,1000}, 0);
- showToast("OK");
- }else{
- //取消震動
- vibrator.cancel();
- showToast("CANCEL");
- }
- }
- });
- tog3.setOnCheckedChangeListener(new OnCheckedChangeListener() {
-
- @Override
- public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
- // TODO Auto-generated method stub
- if(isChecked){
- //設置震動周期
- vibrator.vibrate(new long[]{1000,50,1000,50,1000}, 0);
- showToast("OK");
- }else{
- //取消震動
- 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();
- }
- }

最後別忘了加上
