手机震动的节奏（Vibrator对象及周期运用）

新建一个继承Activity类的VibratorActivity，并设置布局文件为：vibrator.xml。

在布局文件中添加1个EditText和一个Button，EditText用于Vibrator频率的控制

    <EditText

        android:id="@+id/vibrator_edit"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:hint="@string/vibrator_edit_hint"/>

 

    <Button

        android:id="@+id/vibrator_btn"

        style="@android:style/Widget.Button.Inset"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:hint="@string/vibrator_edit_hint"

        android:text="@string/vibrator"/>

最后是Activity代码：

package lyx.feng.third;

 

import lyx.feng.simpletextdemo.R;

import android.app.Activity;

import android.app.Service;

import android.os.Bundle;

import android.os.Vibrator;

import android.text.TextUtils;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

 

public class VibratorActivity extends Activityimplements OnClickListener {

    private EditTextedit = null;

    private Buttonbtn = null;

    private long info[] = null;

    private Vibratorvibrator = null;

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);

       super.setContentView(R.layout.vibrator);

       //得到实例化对象

       this.edit = (EditText)super.findViewById(R.id.vibrator_edit);

       this.btn = (Button)super.findViewById(R.id.vibrator_btn);

       //得到震动服务

       this.vibrator = (Vibrator) getApplication().getSystemService(

              Service.VIBRATOR_SERVICE);

       //注册按钮

       this.btn.setOnClickListener(this);

    }

 

    @Override

    public void onClick(View v) {

       //得到输入框字符串

       String temp = this.edit.getText().toString();

       //判断temp是否为“”或者null，Toast提示

       if (TextUtils.isEmpty(temp)) {

           Toast.makeText(this,"Not Null", Toast.LENGTH_SHORT).show();

           return;

       }

       //划分为Long数组

       String spit[] = temp.split(",");

       this.info =new long[spit.length];

       for (int i = 0; i < spit.length; i++) {

           info[i] = Long.valueOf(spit[i]);

           System.out.print(info[i] +",");

       }

       //开始震动

       this.vibrator.vibrate(info, 0);

    }

}

 

最后还要权限：

<uses-permissionandroid:name="android.permission.VIBRATE"/>
