Android 6.0 运行时权限 easypermissions，permissionsdispatcher ，rxpermissions 的实现

关于android 6.0 运行时权限 ，目前有五种处理方法

危险权限和权限组

gitHub 已上传三种实现方案的Demo https://github.com/pengchengfuGit/PermissionsDemo

1… 采用不理睬的方式将项目的targetSdkVersion 设置为22及以下， 如果设备运行的是 Android 5.1（API 级别 22）或更低版本， 并且应用的 targetSdkVersion 是 22 或更低版本，则系统会在安装时要求用户授予权限。 再次强调，系统只告诉用户应用需要的权限组，而不告知具体权限。 2… 采用系统原生API处理，google原生方案。（采用原生方案，后面会更新。。。。） 3… easypermissions 基于注解，采用反射，影响性能

package com.example.administrator.permissionstest; import android.Manifest; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.util.Log; import android.view.View; import android.widget.TextView; import android.widget.Toast; import java.util.List; import pub.devrel.easypermissions.EasyPermissions; public class EasyActivity extends AppCompatActivity implements EasyPermissions.PermissionCallbacks { private static final int RC_CALL_PHONE = 0; private String TAG= "EasyActivity"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_common); TextView permissions = (TextView) findViewById(R.id.permissions); permissions.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String[] perms = {Manifest.permission.CALL_PHONE}; EasyPermissions.requestPermissions(EasyActivity.this, "直接拨打电话的权限", RC_CALL_PHONE, perms); } }); } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); //Forward results to EasyPermissions Toast.makeText(getApplicationContext(), "onRequestPermissionsResult requestCode" + requestCode, Toast.LENGTH_LONG).show(); EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this); } @Override public void onPermissionsGranted(int requestCode, List<String> perms) { if (perms != null && perms.size() > 0) for (String item : perms) { Log.d(TAG,"onPermissionsGranted "+item); } } @Override public void onPermissionsDenied(int requestCode, List<String> perms) { if (perms != null && perms.size() > 0) for (String item : perms) { Log.d(TAG,"onPermissionsDenied "+item); } } }

4… permissionsdispatcher 基于注解，编译生成类，无反射，不影响性能

package com.example.administrator.permissionstest; import android.Manifest; import android.content.DialogInterface; import android.content.Intent; import android.os.Bundle; import android.support.annotation.NonNull; import android.support.v7.app.AlertDialog; import android.support.v7.app.AppCompatActivity; import android.util.Log; import android.view.View; import android.widget.TextView; import android.widget.Toast; import permissions.dispatcher.NeedsPermission; import permissions.dispatcher.OnNeverAskAgain; import permissions.dispatcher.OnPermissionDenied; import permissions.dispatcher.OnShowRationale; import permissions.dispatcher.PermissionRequest; import permissions.dispatcher.RuntimePermissions; @RuntimePermissions public class DispatcherActivity extends AppCompatActivity { private String TAG = "DispatcherActivity"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_common); TextView permissions = (TextView) findViewById(R.id.permissions); permissions.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Log.d(TAG, "showCameraWithCheck "); DispatcherActivityPermissionsDispatcher.showCameraWithCheck(DispatcherActivity.this); } }); } @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); // NOTE: delegate the permission handling to generated method DispatcherActivityPermissionsDispatcher.onRequestPermissionsResult(this, requestCode, grantResults); } @NeedsPermission(Manifest.permission.CAMERA) void showCamera() { Log.d(TAG, "showCamera "); Intent intent = new Intent(); //调用照相机 intent.setAction("android.media.action.STILL_IMAGE_CAMERA"); startActivity(intent); } @OnShowRationale(Manifest.permission.CAMERA) void showRationaleForCamera(final PermissionRequest request) { Log.d(TAG, "showRationaleForCamera "); new AlertDialog.Builder(this) .setMessage("使用此功能需要打开照相机的权限") .setPositiveButton("允许", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { request.proceed(); } }) .setNegativeButton("拒绝", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { request.cancel(); } }) .show(); } @OnPermissionDenied(Manifest.permission.CAMERA) void showDeniedForCamera() { Log.d(TAG, "showDeniedForCamera "); Toast.makeText(this, "你拒绝了权限，该功能不可用", Toast.LENGTH_SHORT).show(); } @OnNeverAskAgain(Manifest.permission.CAMERA) void showNeverAskForCamera() { Log.d(TAG, "showNeverAskForCamera "); Toast.makeText(this, "用户设置不再询问权限申请", Toast.LENGTH_SHORT).show(); // Toast.makeText(this, " R.string.permission_camera_neverask", Toast.LENGTH_SHORT).show(); } }

5… rxpermissions 基于Rxjava, Rxjava1.0版本跟2.0版本都有（本文采用Rxjava2.0）

package com.example.administrator.permissionstest; import android.Manifest; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.util.Log; import android.view.View; import android.widget.TextView; import android.widget.Toast; import com.tbruyelle.rxpermissions2.Permission; import com.tbruyelle.rxpermissions2.RxPermissions; import io.reactivex.functions.Consumer; import pub.devrel.easypermissions.EasyPermissions; public class RxActivity extends AppCompatActivity{ private String TAG= "RxActivity";//READ_EXTERNAL_STORAGE @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_common); TextView permissions = (TextView) findViewById(R.id.permissions); permissions.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // RxPermissions rxPermission = new RxPermissions(RxActivity.this); requestPermission(); } }); } public void requestPermission(){ RxPermissions rxPermissions = new RxPermissions(this); rxPermissions.requestEach(Manifest.permission.READ_EXTERNAL_STORAGE).subscribe(new Consumer<Permission>() { @Override public void accept(Permission permission) throws Exception { if (permission.granted) { // 用户已经同意该权限 Toast.makeText(getApplicationContext(),"用户已经同意该权限",Toast.LENGTH_SHORT).show(); Log.d(TAG, permission.name + " is granted."); } else if (permission.shouldShowRequestPermissionRationale) { // 用户拒绝了该权限，没有选中『不再询问』（Never ask again）,那么下次再次启动时，还会提示请求权限的对话框 Toast.makeText(getApplicationContext(),"用户拒绝了该权限",Toast.LENGTH_SHORT).show(); Log.d(TAG, permission.name + " is denied. More info should be provided."); } else { // 用户拒绝了该权限，并且选中『不再询问』 Toast.makeText(getApplicationContext(),"用户拒绝了该权限，并且选中『不再询问』",Toast.LENGTH_SHORT).show(); Log.d(TAG, permission.name + " is denied."); } } }); } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); //Forward results to EasyPermissions Toast.makeText(getApplicationContext(), "onRequestPermissionsResult requestCode" + requestCode, Toast.LENGTH_LONG).show(); EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this); } }

PS：本人写的一个小Demo 里面包含了easypermissions，permissionsdispatcher ，rxpermissions 三种插件的用法 permissions Demo
