前言本文主要介绍了关于android实现一键锁屏和一键卸载的相关内容分享出来供大家参考学习这两个功能也是大家在开发中会遇到的两个需求下面话不多说了来一起看看详细的介绍吧。一.设备管理器操作步骤1.创建类DeviceAdminReceiver的子类如com.itheima62.lockscreen.DeviceAdminSample2.在清单文件中配置广播接收者receiverandroid:namecom.itheima62.lockscreen.DeviceAdminSampleandroid:descriptionstring/sample_device_admin_descriptionandroid:labelstring/sample_device_adminandroid:permissionandroid.permission.BIND_DEVICE_ADMINmeta-dataandroid:nameandroid.app.device_adminandroid:resourcexml/device_admin_sample/intent-filteraction android:nameandroid.app.action.DEVICE_ADMIN_ENABLED//intent-filter/receiver3.配置字符串相关信息string nameactivity_sample_device_admin设备管理员/stringstring namesample_device_admin管理员/stringstring namesample_device_admin_description开启设备管理员不开启扣2000块/string4.在res目录下创建xml文件夹在该文件夹下创建device_admin_sample.xml文件内容device-admin xmlns:androidhttp://schemas.android.com/apk/res/androiduses-policieslimit-password/watch-login/reset-password/force-lock/wipe-data/expire-password/encrypted-storage/disable-camera//uses-policies/device-admin5.在代码中创建设备管理器和组件dpm(DevicePolicyManager)getSystemService(DEVICE_POLICY_SERVICE);ComponentName whonewComponentName(this,DeviceAdminSample.class);6.写功能dpm.lockNow();一键锁屏二.源代码创建类DeviceAdminReceiver的子类packagecom.example.suoping;importandroid.app.admin.DeviceAdminReceiver;publicclassDeviceAdminSampleextendsDeviceAdminReceiver{}MainActivitypackagecom.example.suoping;importandroid.app.Activity;importandroid.app.admin.DevicePolicyManager;importandroid.content.ComponentName;importandroid.content.Intent;importandroid.os.Bundle;importandroid.view.Menu;importandroid.view.View;publicclassMainActivityextendsActivity{privateDevicePolicyManager dpm;OverrideprotectedvoidonCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);//setContentView(R.layout.activity_main);dpm(DevicePolicyManager)getSystemService(DEVICE_POLICY_SERVICE);lockScreen(null);}/** * param v * 一键锁屏 */publicvoidlockScreen(View v){//如果没有激活设备管理员提醒给用户做事ComponentName whonewComponentName(this,DeviceAdminSample.class);if(dpm.isAdminActive(who)){dpm.lockNow();//一键锁屏finish();}else{Intent intentnewIntent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,who);intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,设备管理器);startActivityForResult(intent,1);}}OverridepublicbooleanonCreateOptionsMenu(Menu menu){getMenuInflater().inflate(R.menu.main,menu);returntrue;}}RemoveActivitypackagecom.example.suoping;importandroid.app.Activity;importandroid.app.admin.DevicePolicyManager;importandroid.content.ComponentName;importandroid.content.Intent;importandroid.net.Uri;importandroid.os.Bundle;importandroid.view.View;publicclassRemoveActivityextendsActivity{OverrideprotectedvoidonCreate(Bundle savedInstanceState){// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);remove(null);}/** * 一键卸载 * param v */publicvoidremove(View v){// 取消激活设备管理DevicePolicyManager dpm(DevicePolicyManager)getSystemService(DEVICE_POLICY_SERVICE);ComponentName whonewComponentName(this,DeviceAdminSample.class);dpm.removeActiveAdmin(who);//取消激活管理设备//卸载Intent removenewIntent(android.intent.action.DELETE);remove.addCategory(android.intent.category.DEFAULT);remove.setData(Uri.parse(package:getPackageName()));startActivity(remove);//卸载用户apk的界面}}布局文件MainActivity.xmlRelativeLayout
