Android在Android 6.0中不显示录制_音频的权限对话框

Android不显示录制\u音频的权限对话框

我已在android清单中添加了所需的权限

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

并检查它

if (!checkPermission()) {
                requestPermission();
            }

但是，未显示请求权限的对话框或请求权限的屏幕

我正在一个模拟器上测试android 6.0。如果应该显示消息，showldshowRequestPermissionRegulation（）方法只会发出信号。无论其返回值如何，都应请求权限

请看本示例中的第142行：

if (!checkPermission()) {
                requestPermission();
            }
