Android动态权限处理框架

通过APT技术实现Android动态权限框处理架，采用编译期注解，动态生成代码，解决反射注解的性能问题。

在根目录下build.gradle中添加如下代码

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
        google()
        jcenter()
        
    }
}

在需要动态权限的模块中添加依赖

  annotationProcessor  "com.github.itxiaox.permission:permission-processor:1.0.1"
    implementation  "com.github.itxiaox.permission:android-permission:1.0.1"

代码中使用

  package com.itxiaox.permission;

  import android.Manifest;
  import android.os.Bundle;
  import android.view.View;
  import android.widget.Toast;

  import androidx.annotation.NonNull;

  import com.itxiaox.permission.annotation.NeedsPermission;
  import com.itxiaox.permission.annotation.OnNeverAskAgain;
  import com.itxiaox.permission.annotation.OnPermissionDenied;
  import com.itxiaox.permission.annotation.OnShowRationale;
  import com.itxiaox.permission.library.PermissionDialog;
  import com.itxiaox.permission.library.PermissionManager;
  import com.itxiaox.permission.library.listener.PermissionRequest;

  public class MainActivity extends BaseActivity {

  private static final String TAG = "MainActivity";

  String[] permissions = new String[]{Manifest.permission.CAMERA,
          Manifest.permission.WRITE_EXTERNAL_STORAGE
          , Manifest.permission.READ_EXTERNAL_STORAGE};

  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);


  }

  public void camera(View view) {
      PermissionManager.request(this, permissions);
  }

  /**
   * 权限通过的注解
   */
  @NeedsPermission()
  void showCamera() {
      Toast.makeText(MainActivity.this, "获取到权限", Toast.LENGTH_SHORT).show();
  }

  /**
   * 权限拒绝的注解
   */
  @OnPermissionDenied()
  public void denied() {
      Toast.makeText(MainActivity.this, "权限被拒绝：", Toast.LENGTH_SHORT).show();

  }

  /**
   * 权限说明的拒绝，一般这里可以采用一个对话框说明该权限的作用
   *
   * @param request
   */
  @OnShowRationale()
  void showRationaleForCamera(final PermissionRequest request) {
      //再次请求权限
      //request.proceed();
      PermissionDialog.showRationale(this, request,
              "权限说明", "您需要此权限进行相关操作");
  }

  @OnNeverAskAgain()
  void onNeverAgain() {
      PermissionDialog.showNeverAgain(this, "权限已拒绝",
              "您已经拒接了相关权限，请去设置中开启");
  }

  @Override
  public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
      super.onRequestPermissionsResult(requestCode, permissions, grantResults);
      PermissionManager.onRequestPermissionsResult(this, requestCode, grantResults);
  }

}
