Android 运行时权限流程：我可以使用 ActivityCompat.requestPermissions 发送额外内容吗？

【中文标题】Android 运行时权限流程：我可以使用 ActivityCompat.requestPermissions 发送额外内容吗？

【英文标题】：Android runtime permissions process: Can I send extras with ActivityCompat.requestPermissions?

【发布时间】：2018-01-24 18:11:37

【问题描述】：

在请求授予 android 的危险权限期间，是否有任何方法可以发送 bundle/extras（就像我们对意图所做的那样）？

在为android授予危险权限的正常过程中，我们应该调用ActivityCompat.requestPermissions(...)，根据documentation定义如下：

void requestPermissions (Activity activity, String[] permissions,int requestCode)

可以看出，在权限请求中没有发送任何额外信息的选项。目前我在我的活动中使用静态参数来在我的权限被授予后恢复它们。

我想知道有什么选择吗？

【参考方案1】：

我以这种方式包含意图，第一部分代码只是检查我们是否有 SD 卡

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) 
        if (checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) 
            //.... write file into storage ...
            System.out.println("SDK > BuildVersion TRUE");
         else 
            requestPermissions(new String[]Manifest.permission.WRITE_EXTERNAL_STORAGE, 666);  // Comment 26
            System.out.println("go to requestPermissions");
        
    
    onLoad();


@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) 

    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) 

        case 666: // Allowed was selected so Permission granted
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) 

                Snackbar s = Snackbar.make(findViewById(android.R.id.content),"Permission Granted",Snackbar.LENGTH_LONG);
                View snackbarView = s.getView();
                TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
                textView.setTextColor(Color.RED);
                textView.setTextSize(18);
                textView.setMaxLines(6);
                s.show();

                // do your work here

             else if (Build.VERSION.SDK_INT >= 23 && !shouldShowRequestPermissionRationale(permissions[0])) 
                // User selected the Never Ask Again Option Change settings in app settings manually
                AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);
                alertDialogBuilder.setTitle("Change Permissions in Settings");
                alertDialogBuilder
                        .setMessage("Click SETTINGS to Manually Set\n\n"+"Permissions to use Database Storage")
                        .setCancelable(false)
                        .setPositiveButton("SETTINGS", new DialogInterface.OnClickListener() 
                            public void onClick(DialogInterface dialog, int id) 
                                Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                                Uri uri = Uri.fromParts("package", getPackageName(), null);
                                intent.setData(uri);
                                startActivityForResult(intent, 1000);     // Comment 3.
                            
                        );

                AlertDialog alertDialog = alertDialogBuilder.create();
                alertDialog.show();

             else 
                    // User selected Deny Dialog to EXIT App ==> OR <== RETRY to have a second chance to Allow Permissions
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED) 

                    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);
                    alertDialogBuilder.setTitle("Second Chance");
                    alertDialogBuilder
                            .setMessage("Click RETRY to Set Permissions to Allow\n\n"+"Click EXIT to the Close App")
                            .setCancelable(false)
                            .setPositiveButton("RETRY", new DialogInterface.OnClickListener()

                                    Intent i = new Intent(MainActivity.this,MainActivity.class);
                                    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
                                    startActivity(i);
                                    
                            )
                            .setNegativeButton("EXIT", new DialogInterface.OnClickListener()

                                    finish();
                                    dialog.cancel();
                                
                            );
