Passing Image Through Intent. getting error: java.lang.NumberFormatException: Invalid int: "null"

Question

我的 Application 中有两个 Activities，我想通过意图将 Image title 和 image 本身传递给同一个 [=] 的 second activity 18=]。但我收到以下错误： java.lang.NumberFormatException: Invalid int: "null" 在下行

Glide.with(getApplicationContext()).load(Integer.parseInt(intent.getStringExtra("Image"))).into(imageView);

Activity1个代码：

 public void cardClicked(final  Sport  currentSport){
            itemCard.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                        Intent intent = new Intent(context, DetailActivity.class);
                        intent.putExtra("Image",R.drawable.img_baseball);
                        intent.putExtra("Name",currentSport.getTitle());

                        context.startActivity(intent);
                    }
            });


        }

第二个Activity代码：

private ImageView imageView;
    private TextView nameView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_detail);
        imageView = findViewById(R.id.tv_image);
        nameView = findViewById(R.id.tv_name);
        Intent intent = getIntent();
        nameView.setText(String.valueOf(intent.getStringExtra("Name")));
       Glide.with(getApplicationContext()).load(Integer.parseInt(intent.getStringExtra("Image"))).into(imageView);

    }

Answer 1

尽管您希望使用 int，但您正在使用 intent.getStringExtra(String)。所以正确的是使用 intent.getIntExtra(String, int).
