屏幕锁定和恢复出厂设置

1.创建 MyAdmin 的广播接受者继承 DeviceAdminReceiver

       <receiver android:name=".MyAdmin">
           <meta-data android:name="android.app.device_admin"
                android:resource="@xml/my_admin" />
           <intent-filter>
               <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
           </intent-filter>
       </receiver>

res文件夹下创建xml文件夹，xml文件里创建my_admin.xml文件
my_admin.xml

<?xml version="1.0" encoding="utf-8"?>
<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
        <uses-policies>
                <limit-password />
                <watch-login />
                <reset-password />
                <force-lock />
                <wipe-data />
        </uses-policies>
</device-admin>

2.获取IDevicePolicyManager

DevicePolicyManager dm = (DevicePolicyManager) getSystemService(DEVICE_POLICY_SERVICE);

3.注册广播接受者为admin设备
ComponentName mAdminName = new ComponentName(this, MyAdmin.class);
if (mService != null) {

//先判断是否已经激活
       if (!mService.isAdminActive(mAdminName)) {
                   Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
                   intent.putExtra (DevicePolicyManager.EXTRA_DEVICE_ADMIN,mAdminName);
                   startActivity(intent);
               }

}

4.点击事件中进行锁屏或者清零数据处理

dm.resetPassword("123", 0); //设置锁屏密码，“123”为设置的密码

dm.lockNow();//锁屏

dm.wipeData(0);//恢复出厂设置，0改为1可清除手机和sd卡的数据

dm.removeActiveAdmin(mAdminName)//设置为非激活状态
