Question

我添加了

   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
     <uses-permission android:name="android.Manifest.permission.RECORD_AUDIO"/>
     <uses-permission android:name="android.Manifest.permission.READ_EXTERNAL_STORAGE" />
     <uses-feature android:name="android.hardware.microphone" android:required="false" />

在Manifest。

在检查后的活动中未授予权限我正在请求

 ActivityCompat.requestPermissions(Main2Activity.this, new String[]{Manifest.permission.RECORD_AUDIO, Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_RECORD_AUDIO_PERMISSION);

开始申请。显示存储权限，但不显示音频记录权限。即使在应用程序中也不显示 - ＆gt;权限。

请帮我解决这个问题。

Answer 1

首先checkSelfPermission。

if (ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.RECORD_AUDIO}, MY_PERMISSIONS_RECORD_AUDIO);
}

在Android清单中更改：

<uses-permission android:name="android.Manifest.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.Manifest.permission.READ_EXTERNAL_STORAGE" />

为：

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

请求运行时权限

//Create placeholder for user's consent to record_audio permission.
//This will be used in handling callback
private final int MY_PERMISSIONS_RECORD_AUDIO = 1;

private void requestAudioPermissions() {
    if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.RECORD_AUDIO)
            != PackageManager.PERMISSION_GRANTED) {

        //When permission is not granted by user, show them message why this permission is needed.
        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.RECORD_AUDIO)) {
            Toast.makeText(this, "Please grant permissions to record audio", Toast.LENGTH_LONG).show();

            //Give user option to still opt-in the permissions
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.RECORD_AUDIO},
                    MY_PERMISSIONS_RECORD_AUDIO);

        } else {
            // Show user dialog to grant permission to record audio
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.RECORD_AUDIO},
                    MY_PERMISSIONS_RECORD_AUDIO);
        }
    }
    //If permission is granted, then go ahead recording audio
    else if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.RECORD_AUDIO)
            == PackageManager.PERMISSION_GRANTED) {

        //Go ahead with recording audio now
        recordAudio();
    }
}

//Handling callback
@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_RECORD_AUDIO: {
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted, yay!
                recordAudio();
            } else {
                // permission denied, boo! Disable the
                // functionality that depends on this permission.
                Toast.makeText(this, "Permissions Denied to record audio", Toast.LENGTH_LONG).show();
            }
            return;
        }
    }
}

感谢您的所有答案。问题是我的中间人没有被删除所以Clean Build没有发生。完成后，我的代码按预期工作。

在启动应用程序时，我的应用程序中不显示记录音频权限
