系統獲取Vibrator也是調用Context的getSystemService方法,接下來就可以調用Vibrator的方法控制手機振動了。Vibrator只有三個方法控制手機振動:
1、vibrate(long milliseconds):控制手機振動的毫秒數。
2、vibrate(long[] pattern,int repeat):指定手機以pattern模式振動,例如指定pattern為new long[]{400,800,1200,1600},就是指定在400ms、800ms、1200ms、1600ms這些時間點交替啟動、關閉手機振動器,其中repeat指定pattern數組的索引,指定pattern數組中從repeat索引開始的振動進行循環。-1表示只振動一次,非-1表示從pattern的指定下標開始重復振動。
3、cancel():關閉手機振動
下面通過一個示例來演示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); // 獲取系統的Vibrator服務 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) { // 設置震動周期 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) { // 設置震動時長 vibrator.vibrate(5000); } } else { // 關閉震動 vibrator.cancel(); } } }
