在SO上已经有很多关于这个主题的许多 问题，我知道。然而，到目前为止，我找到的所有答案都没有解决我的问题。
问题：
ActivityCompat.requestPermissions不会触发弹出窗口，请求用户允许通知权限。
设置：
- 在物理设备上进行测试（Android 13，Pixel 6）
- 目标SDK版本为33（targetSdkVersion=33）
- minSdkVersion = 29
- AndroidManifest具有权限：
<uses-permission android:name="android.permission.POST_NOTIFICATION" /> - 在一个正常工作的Activity的onCreate中，我执行：
if (ContextCompat.checkSelfPermission(this, Manifest.permission.POST_NOTIFICATIONS) == PackageManager.PERMISSION_DENIED)
{
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.POST_NOTIFICATIONS}, 1);
}
回调函数的格式如下：
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case 1:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(MainScreenActivity.this, "Woho, you have enabled notifications!", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(MainScreenActivity.this, "Ouch, this is gonna hurt without notifications", Toast.LENGTH_SHORT).show();
}
return;
}
}

我通过调试��逐步执行了代码，并确认requestPermissions已被执行，但是onRequestPermissionsResult立即触发，设备上没有弹出窗口。
我还阅读了this，但我认为这是由于开发人员未按照here中描述的选择加入模型，但也许，这真的是一个问题吗？因为我无法理解这个...
更新
我在应用程序的其他部分请求其他权限，这行代码运行良好-我得到弹出窗口以授予权限：
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, BaseActivity.PHONE_STATE_PERMISSION_CODE);
更新 2
在代码库的另一部分，我有相同的 requestPermission 调用，但是针对另一个权限，这个调用起作用了：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, BaseActivity.PHONE_STATE_PERMISSION_CODE);
}
当执行此代码时，我会得到以下结果：
但是，如果我将requestPermissions调用更改为以下内容，则不会发生任何事情，并且我立即进入回调函数，显示“rejected”：@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.POST_NOTIFICATIONS}, BaseActivity.PHONE_STATE_PERMISSION_CODE);
}

我也尝试使用新的ActivityResultLauncher，但行为是相同的 - 它直接转到回调而没有显示任何弹出窗口。
