我用这个Topic

我尝试此代码,但没有用：

PACKAGE_NAME = context.getApplicationContext().getPackageName();

try {
  pi = context.getPackageManager().getPackageInfo(PACKAGE_NAME,PackageManager.GET_PERMISSIONS);
  for (String perm : pi.requestedPermissions) {
    Log.e("Foo",perm);
  }
} catch (Exception e) {
}

但这不能帮助我.我有应用程序列表,我想获得在每个应用程序上使用的权限.
我该如何处理？

更新：
就像照片一样,当我单击“دسترسیها”时,我想获得该应用程序中使用的权限.(例如,电报中：Internet,存储,通话,摄像头…)

更新2：

我将分享我的问题的适配器代码

我的适配器：

class AppViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {



    AppViewHolder(View itemView,Context context,List<App> apps) {
      super(itemView);
      txt_show_permission = itemView.findViewById(R.id.txt_show_permission);



      /*The String Buffer For Permissions*/
      appNameAndPermissions = new StringBuffer();
      PackageManager pm = context.getPackageManager();
      List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_Meta_DATA);
      for (ApplicationInfo applicationInfo : packages) {
        Log.d(TAG,"App: " + applicationInfo.name + " Package: " + applicationInfo.packageName);

        PackageInfo packageInfo = null;
        try {
          packageInfo = pm.getPackageInfo(applicationInfo.packageName,PackageManager.GET_PERMISSIONS);
          appNameAndPermissions.append(packageInfo.packageName + "*******:\n");


          //Get Permissions
          requestedPermissions = packageInfo.requestedPermissions;

          if (requestedPermissions != null) {
            for (int i = 0; i < requestedPermissions.length; i++) {
              Log.d(TAG,requestedPermissions[i]);
              appNameAndPermissions.append(requestedPermissions[i] + "\n");
            }

            appNameAndPermissions.append("\n");
          }

        } catch (PackageManager.NameNotFoundException e) {
          e.printStackTrace();
        }


      }
    }

在onBindViewHolder中的txt_show_permission上设置点击监听器：

holder.txt_show_permission.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {

        showDialog(String.valueOf(appNameAndPermissions));

      }
    });

适配器类中对话框的方法：

 public void showDialog(String txtPermission) {
    final Dialog dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setCancelable(false);
    dialog.setContentView(R.layout.show_permission_dialog);

    TextView txt_permission = dialog.findViewById(R.id.txt_permission);
    Button btn_ok = dialog.findViewById(R.id.btn_ok);
    txt_permission.setText(txtPermission);

    btn_ok.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        dialog.dismiss();
      }
    });
    dialog.show();

  }
