android - 如何列出传递另一个 Activity 的图像

Question

我是 android 开发的初学者。 这是我的列表图像代码。 它不会将图像传递给另一个 Activity 。为什么它不将图像传递给另一个 Activity 。谁能修好它？

public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = getLayoutInflater();

        View row = inflater.inflate(R.layout.row, parent, false);

        TextView textview = (TextView) row.findViewById(R.id.tvTop);
        ImageView imageview = (ImageView) row.findViewById(R.id.list_image);

        textview.setText(data_topText[position]);
        imageview.setImageResource(data_image[position]);

        row.setOnClickListener(new OnClickListener() {

            public void onClick(View row) {
                    TextView textview = (TextView) row.findViewById(R.id.tvTop);
                    ImageView imageview = (ImageView) row.findViewById(R.id.list_image);


                    String product = textview.getText().toString();
                    int images = imageview.getId();


                    Intent i = new Intent(getApplicationContext(),
                            SecondScreenActivity.class);

                    i.putExtra("name", product);
                    i.putExtra("zurag", images);
                    startActivity(i);
            }
        });

        return (row);

    }

这是 SecondScreenActivity.java:

public class SecondScreenActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.screen2);

    TextView txtName = (TextView) findViewById(R.id.txtName);
    ImageView images = (ImageView) findViewById(R.id.image);

    Intent intent = getIntent();

    String name = intent.getStringExtra("name");
    int pic =intent.getIntExtra("zurag", 0);

    txtName.setText(name);
    images.setImageResource(pic);

}

不要为您的行使用 setOnClickListener()，请尝试为您的 ListView 使用 setOnItemClickListener():

lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View row, int position, long id) {
                TextView textview = (TextView)row.findViewById(R.id.tvTop);
                    ImageView imageview = (ImageView) row.findViewById(R.id.list_image);


                    String product = textview.getText().toString();
                    int images = imageview.getId();


                    Intent i = new Intent(getApplicationContext(),
                            SecondScreenActivity.class);

                    i.putExtra("name", product);
                    i.putExtra("zurag", images);
                    startActivity(i);

            }

        });
