手机震动的节奏（Vibrator对象及周期运用）

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 Activity implements OnClickListener {     private EditText edit = null;     private Button btn = null;     private long info[] = null;     private Vibrator vibrator = 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-permission
android:name="android.permission.VIBRATE"
/>
