1.首先创建一个类DeviceAdminSample继承DeviceAdminReceiver(android.app.admin.DeviceAdminReceiver),作为接收广播信息的处理类(其实不用实现,主要内部也是维护了DevicePolicyManager类的实例,主要操作的功能是这个类的内部方法实现的)
package com.example.deviceadmi;
import android.app.admin.DeviceAdminReceiver;
import android.content.Context;
import android.content.Intent;
public class DeviceAdminSample extends DeviceAdminReceiver {
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
}
}
2.在清单配置文件上配置receiver信息
<receiver
android:name="com.example.deviceadmi.DeviceAdminSample"
android:description="@string/sample_device_admin_description"
android:label="@string/sample_device_admin"
android:permission="android.permission.BIND_DEVICE_ADMIN" >
<meta-data
android:name="android.app.device_admin"
android:resource="@layout/device_admin_sample" /><!--device_admin_sample的xml文件需要创建-->
<intent-filter>
<action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
</intent-filter>
</receiver>
3.创建device_admin_sample.xml文件
<?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 />
<expire-password />
<encrypted-storage />
<disable-camera />
</uses-policies>
</device-admin>
4.在activity上直接创建调用就可以
package com.example.deviceadmi;
import android.app.admin.DevicePolicyManager;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
private ComponentName mDeviceAdminSample;
private DevicePolicyManager mDPM;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn_active=(Button) findViewById(R.id.btn_active);
Button btn_lock=(Button) findViewById(R.id.btn_lock);
Button btn_wipedata=(Button) findViewById(R.id.btn_wipedata);
Button btn_unintall=(Button) findViewById(R.id.btn_unintall);
mDeviceAdminSample = new ComponentName(this, DeviceAdminSample.class);
mDPM = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
btn_active.setOnClickListener(new OnClickListener() {
//调用设备管理器的页面显示,激活需要自己点击
@Override
public void onClick(View v) {
Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mDeviceAdminSample);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,"设备管理器");
startActivity(intent);
}
});
btn_lock.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (mDPM.isAdminActive(mDeviceAdminSample)) {//判断定义好的组件是否开启激活了
mDPM.lockNow();
mDPM.resetPassword("123", 0);
}else{
Toast.makeText(getApplicationContext(), "还没有激活设备管理器", Toast.LENGTH_LONG).show();
}
}
});
btn_wipedata.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO 模拟器是没有进行数据的清除的,真机才会清除数据
if (mDPM.isAdminActive(mDeviceAdminSample)) {
mDPM.wipeData(0);//清除手机内部存储的数据
// mDPM.wipeData(DevicePolicyManager.WIPE_EXTERNAL_STORAGE);//清除手机外部存储的数据
} else {
Toast.makeText(getApplicationContext(), "还没有激活设备管理器", Toast.LENGTH_LONG).show();
}
}
});
/**
* 卸载页面的调用
* <activity android:name=".UninstallerActivity"
android:configChanges="orientation|keyboardHidden"
android:theme="@style/TallTitleBarTheme">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.DELETE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="package" />
</intent-filter>
</activity>
*/
btn_unintall.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent("android.intent.action.DELETE");
intent.addCategory("android.intent.category.DEFAULT");
intent.setData(Uri.parse("package:"+getPackageName()));//卸载当前的应用
startActivity(intent);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
activity_main.xml布局文件
<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:orientation="vertical"
tools:context="com.example.deviceadmi.MainActivity" >
<Button
android:id="@+id/btn_active"
android:text="一键开启"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<Button
android:id="@+id/btn_lock"
android:text="一键锁屏"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<Button
android:id="@+id/btn_wipedata"
android:text="一键清除数据"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<Button
android:id="@+id/btn_unintall"
android:text="一键卸载"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
