手机震动的节奏

 手机震动可以是一种提醒或是替换铃声的事件，如果想要让手机乖乖的震动，需要创建Vibrator对象通过Vibrator方法来实现达到震动的模式，在Vibrator的构造方法中有四个参数前三个值是设置震动的大小，可以把数值改成一大一小这样就可以明显感觉到震动的差异，而最后一个值是震动的时间，  Repeat=0时，震动会一直持续repeat=-1震动只会出现一轮，运动完毕后就不再震动

判断ToggleButton是否被开启。如果单击就是“ON”就会启动震动模式如果点击OFF就会关闭振动模式

先定义一个Activity

 

package cn.hwttnet.com.ui;

import android.app.Activity;
import android.app.Service;
import android.os.Bundle;
import android.os.Vibrator;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Toast;
import android.widget.ToggleButton;

public class EX05_06Activity extends Activity {

	private Vibrator vbt;
	private ToggleButton tb1, tb2, tb3;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		vbt = (Vibrator) getApplication().getSystemService(
				Service.VIBRATOR_SERVICE);
		final ToggleButton tb1 = (ToggleButton) findViewById(R.id.toggleButton1);
		final ToggleButton tb2 = (ToggleButton) findViewById(R.id.toggleButton2);
		final ToggleButton tb3 = (ToggleButton) findViewById(R.id.toggleButton3);
		//短震动
		tb1.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				if (tb1.isChecked()) {

					vbt.vibrate(new long[] { 100, 10, 100, 1000 }, -1);
					Toast.makeText(getApplicationContext(), "震动开启",
							Toast.LENGTH_LONG).show();
				} else {
					vbt.cancel();
					Toast.makeText(getApplicationContext(), "震动取消",
							Toast.LENGTH_LONG).show();
				}
			}
		});
		//长震动
		tb2.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				if (tb2.isChecked()) {

					vbt.vibrate(new long[] { 100, 100, 100, 1000 }, 0);
					Toast.makeText(getApplicationContext(), "震动开启",
							Toast.LENGTH_LONG).show();
				} else {
					vbt.cancel();
					Toast.makeText(getApplicationContext(), "震动取消",
							Toast.LENGTH_LONG).show();
				}
			}
		});
		//节奏震动
		tb3.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				if (tb3.isChecked()) {

					vbt.vibrate(new long[] { 1000, 50, 1000, 50,1000 }, 0);
					Toast.makeText(getApplicationContext(), "震动开启",
							Toast.LENGTH_LONG).show();
				} else {
					vbt.cancel();
					Toast.makeText(getApplicationContext(), "震动取消",
							Toast.LENGTH_LONG).show();
				}
			}
		});
	}
}

 

定义一个main.xml

 

然后震动事件必须允许android .permission.VIBARTE权限

试着把震动的大小做多变化的改变在long[]里面多做一些变化

tb3.vibrate(new long[]{10000,500,10000,500,10000,500,10000},0);
