Fragment中申请权限并onRequestPermissionsResult回调

权限申请是Fragment自身去申请

代码如下:

//by lxy modify
    private void startFolderActivity(int pos) {
        index = pos;
        if (SplashActivity.checkPermission(getContext(), Manifest.permission.WRITE_EXTERNAL_STORAGE) &&
                SplashActivity.checkPermission(getContext(), Manifest.permission.READ_EXTERNAL_STORAGE)){
            stratGo(pos);
        }else{
            FolderFragment.this.requestPermissions(new String[]{
                    Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE},1);
        }
    }
    private void stratGo(int pos){
        String path = extendedMemoryPath.get(pos);
        File file = new File(path);
        if (!file.exists()) return;
        Intent intent = new Intent(activity, FolderActivity.class);
        intent.putExtra("filePath", path);
        intent.putExtra("rootName", file.getName());
        startActivity(intent);
    }

权限结果回调

@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case SplashActivity.PERMISSION_REQUEST_CODE:
                if (grantResults.length > 0 && grantResults[0] != PackageManager.PERMISSION_GRANTED){
                    ToastUtil.showToast(getContext(),getString(R.string.permission_denied));
                    return;
                }
                if (index>=0){
                    String path = extendedMemoryPath.get(index);
                    File file = new File(path);
                    if (!file.exists()) return;
                    Intent intent = new Intent(activity, FolderActivity.class);
                    intent.putExtra("filePath", path);
                    intent.putExtra("rootName", file.getName());
                    startActivity(intent);
                }
                break;
            default:
                break;
        }
    }
