1.在Activity中：

final static int ENABLE_ADMIN = 1;
final static int SUCESS = -1;
private ComponentName mAdminName = null;

onCreat中
mAdminName = new ComponentName(this, AdminManageReceiver.class);
DevicePolicyManager mDPM = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);//在设备上执行管理政策
if (!mDPM.isAdminActive(mAdminName)) {//如果未激活
    Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);//打开手机设备管理器的intent
    intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
    intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,
            "asjdk");
    startActivityForResult(intent, ENABLE_ADMIN);
}
if (mDPM.isAdminActive(mAdminName)) {
    mDPM.lockNow();//执行锁屏
} else {
    Log.e("screenlock", "Unable to lock the phone D:");
}
2：在Receiver中写
public class AdminManageReceiver extends DeviceAdminReceiver {
}
里面什么都不用写。

3：manifist中写：

<receiver
    android:name=".service.AdminManageReceiver"
    android:label="@string/app_name"
    android:permission="android.permission.BIND_DEVICE_ADMIN" >
    <meta-data
        android:name="android.app.device_admin"
        android:resource="@xml/device_admin" />

    <intent-filter>
        <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
    </intent-filter>
</receiver>
和<activity android:name=".activity.ADActivity"
    android:theme="@android:style/Theme.NoDisplay"
    android:label="@string/app_name"
    android:excludeFromRecents="true" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.LAUNCHER" />
        <action android:name="android.intent.action.ASSIST" />
    </intent-filter>
</activity>
4：在res中创建xml文件，中再创建device_admin.xml
<?xml version="1.0" encoding="utf-8"?>
<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-policies>
        <force-lock />  //强制锁屏,这里还可以配置其他的如恢复出厂设置、设置密码
    </uses-policies>
</device-admin>
