开关机压力测试APK学习

        楼主身在一个手机方案公司，最近在查看一个开关机压力测试的APK，记录一下，学习一下别人的代码。功能单一，代码简单，谢谢！

布局界面较简单，一个ListView里面含有三个Textiew，一个设置总的重启次数，一个重启开关，一个用于显示标记已经重启的次数。这里就不写出了。

程序代码比较简单。此外还有一个java文件。

package com.zh.reboot;

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.util.Log;

public class BootBroadcastReceiver extends BroadcastReceiver {
/** Called when the activity is first created. */
static final String ACTION = "android.intent.action.BOOT_COMPLETED";//开机就启动，接收这个ACTION，检测是否需要继续开关机测试
private String TAG = "Reboot";

@Override
public void onReceive(Context content, Intent intent) {
// TODO Auto-generated method stub
if (intent.getAction().equals(ACTION)) {
SharedPreferences sp = content.getSharedPreferences("datafile",
Context.MODE_PRIVATE);
int count = sp.getInt("count", 0);
int needreboot = sp.getInt("need_reboot",
mainActivity.NOT_NEED_REBOOT);
int totalnum = sp.getInt("totalnum", -1);
Log.d(TAG, "count:" + count + " need_reboot:" + needreboot
+ " totalnum:" + totalnum);
if (count != 0 && needreboot == mainActivity.NEED_REBOOT
&& count != totalnum) {
Intent AutoRebootIntent = new Intent(content,
mainActivity.class);
AutoRebootIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
content.startActivity(AutoRebootIntent);
}
}
}
}

相关部分已经说明，很好理解。欢迎留言。留做标记，以后好找。
