代碼也很簡單,布局的話就四個簡單的按鈕而已

activity_main.xml:

重寫onClick方法,根據不同的view的id就可以判斷是哪個按鈕點擊了,這種寫法的好處是對於組件較多的

情況這樣寫可以簡化代碼！

MainActivity.java:

package com.jay.example.vibratordemo;

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.Button;
import android.widget.Toast;


public class MainActivity extends Activity implements OnClickListener{

	private Button btnshort;
	private Button btnlong;
	private Button btnrhythm;
	private Button btncancel;
	private Vibrator myVibrator;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		btnshort = (Button) findViewById(R.id.btnshort);
		btnlong = (Button) findViewById(R.id.btnlong);
		btnrhythm = (Button) findViewById(R.id.btnrhythm);
		btncancel = (Button) findViewById(R.id.btncancle);
		
		btnshort.setOnClickListener(this);
		btnlong.setOnClickListener(this);
		btnrhythm.setOnClickListener(this);
		btncancel.setOnClickListener(this);
		
		
		//獲得系統的Vibrator實例:
		myVibrator = (Vibrator) getSystemService(Service.VIBRATOR_SERVICE);
		
	}

	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.btnshort:
			myVibrator.cancel();
			myVibrator.vibrate(new long[]{100,200,100,200}, 0);
			Toast.makeText(getApplicationContext(), "短振動", Toast.LENGTH_SHORT).show();
			break;
		case R.id.btnlong:
			myVibrator.cancel();
			myVibrator.vibrate(new long[]{100,100,100,1000}, 0);
			Toast.makeText(getApplicationContext(), "長振動", Toast.LENGTH_SHORT).show();
			break;
		case R.id.btnrhythm:
			myVibrator.cancel();
			myVibrator.vibrate(new long[]{500,100,500,100,500,100}, 0);
			Toast.makeText(getApplicationContext(), "節奏振動", Toast.LENGTH_SHORT).show();
			break;
		case R.id.btncancle:
			myVibrator.cancel();
			Toast.makeText(getApplicationContext(), "取消振動", Toast.LENGTH_SHORT).show();
		}
		
	}
}

好了,基本用法其實也是很簡單的,這裡就不多說了,另外上面也說了,虛擬機是沒有震動效果的,所以

需要把應用發布到手機上才能檢測效果了!參考代碼下載:vibratorDemo.rar

為了方便各位,直接把apk導出來吧,直接下載安裝到手機就可以測試效果了,當然只是個小demo,不會

推送廣告,亂發短信什麼的=-=!安裝時可以查看所需要的權限!apk下載:vibratorDemo.apk
