1,刚出现这样的问题我是直接把 CAMERA 移除掉

2.第一步判断时候授权。

if (Build.VERSION.SDK_INT >= 23) {
    int checkCallPhonePermission = ContextCompat.checkSelfPermission(AppointmentDetailActivity.this, Manifest.permission.CAMERA);
    if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
        ActivityCompat.requestPermissions(AppointmentDetailActivity.this,new String[]{Manifest.permission.CAMERA},OPEN_CANMER);
        return;
    }else{
        showCamera();
    }
} else {
    showCamera();
}

第二步接收返回的结果。

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case OPEN_CANMER:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                showCamera();
            } else {
                Toast.makeText(AppointmentDetailActivity.this, "相机权限禁用了。请务必开启相机权", Toast.LENGTH_SHORT).show();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}
