Question

我正在尝试调用用户在运行时启用其写入外部存储权限。我使用了以下代码。它显示运行时权限对话框。当我点击允许或拒绝时，它不会调用onReqestPermissionResult（回调方法）方法。

我必须为此做些什么？

public class PermissionCheck extends Activity {

    private static final String TAG = "PermissionCheck";

    private Fragment mFragment;
    private Activity mActivity;

    public PermissionCheck(Fragment fragment){
        mFragment = fragment;
        mActivity = fragment.getActivity();
    }

    public boolean isStoragePermissionGranted() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if (PackageManager.PERMISSION_GRANTED == ContextCompat.checkSelfPermission(mActivity, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                return true;
            } else {
                ActivityCompat.requestPermissions(mActivity, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
                return false;
            }
        }
        else {
            return true;
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if(grantResults[0] == PackageManager.PERMISSION_GRANTED){
            Log.v(TAG,"Permission: "+permissions[0]+ "was "+grantResults[0]);
        }
    }
}

Answer 1

您正在requestPermissions中传递另一个活动的实例，因此onRequestPermissionResult会调用mActivity，而不是PermissionCheck。尝试将requestPermissions更改为：

ActivityCompat.requestPermissions(PermissionCheck.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);

Answer 2

替换：

<dependency>
  <groupId>org.glassfish.jersey.media</groupId>
  <artifactId>jersey-media-json-jackson</artifactId>
  <version>2.25</version>
</dependency>

使用：

ActivityCompat.requestPermissions(mActivity, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);

将onRequestPermissionsResult（）替换为：

 ActivityCompat.requestPermissions(PermissionCheck.this, new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);

在Android动态权限中没有调用onReqestPermissionResult
