Question

我无法允许其他应用获取权限。它向我显示允许权限的窗口，但我无法切换开关，它被禁用。我检查了其他答案，它没有帮助我，我使用了与其他讨论相同的解决方案，但它不起作用。

这是我的代码：

单击按钮时，将调用launchMainservice

 btntest.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                hours = hours*3600000;
                mins = mins*60000;
                duration = hours+mins;
                Toast.makeText(Main2Activity.this,"duration: "+duration,LENGTH_LONG).show();
                StartService(duration);
                launchMainService();
                btntest.setClickable(false);
            }
        });

launchMainService（）：

 public void launchMainService() {
        if (Settings.canDrawOverlays(this)) {

            Toast.makeText(this,"service is working",Toast.LENGTH_LONG).show();
            Intent svc = new Intent(this, Service2.class);
            startService(svc);
        }
        else {


            Toast.makeText(this,"check permission",Toast.LENGTH_LONG).show();
            checkDrawOverlayPermission();
        }

    }

    public final static int REQUEST_CODE = 10101;

    public void checkDrawOverlayPermission() {


        if (!Settings.canDrawOverlays(this)) {

            Toast.makeText(this,"setting another permission",Toast.LENGTH_LONG).show();

            Intent intent123 = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName()));
            startActivityForResult(intent123, REQUEST_CODE);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode,  Intent data) {


        if (requestCode == REQUEST_CODE) {
            Toast.makeText(this,"request code received",Toast.LENGTH_LONG).show();
            // Double-check that the user granted it, and didn't just dismiss the request
            if (Settings.canDrawOverlays(this)) {


                launchMainService();
            }
            else {
                Toast.makeText(this, "Sorry. Can't draw overlays without permission...", Toast.LENGTH_SHORT).show();
            }
        }
        Toast.makeText(this,"failed to receive request code",Toast.LENGTH_LONG).show();
    }

对于子孙后代，我遇到了同样的问题。问题是我无意中请求了权限的名称Manifest.permission.SYSTEM_ALERT_WINDOW，而不是值android.permission.SYSTEM_ALERT_WINDOW。由于清单也未在此处发布，因此很可能是OP遇到的相同问题。

我无法为我的应用
