Android中振動器(Vibrator)的使用
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: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();
}
}
