Android中振动器(Vibrator)的使用

jopen 11年前

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:

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();            }            }    }
