import android.widget.AdapterView;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.TextView;

import java.util.List;

public class DisplayListView extends AppCompatActivity {

    String JSON_STRING;
    JSONObject jsonObject;
    JSONArray jsonArray;
    ContactAdapter contactAdapter;
    ListView listView;
    TextView lstv;
    String username,email,password,name,last;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.display_listview_layout);


        listView = (ListView) findViewById(R.id.list);
        lstv = (TextView) findViewById(R.id.lstv);

        contactAdapter = new ContactAdapter(this, R.layout.row_layout);
        listView.setAdapter(contactAdapter);

        JSON_STRING = getIntent().getExtras().getString("json_data");


        try {
            jsonObject = new JSONObject(JSON_STRING);
            jsonArray = jsonObject.getJSONArray("server_response");


            int count = 0;


            while(count<jsonArray.length()){

                JSONObject JO = jsonArray.getJSONObject(count);
                username = JO.getString("username");
                email = JO.getString("email");
                password = JO.getString("password");
                name = JO.getString("name");
                last = JO.getString("lastname");

                Contacts contacts = new Contacts(username,email,password,name,last);
                contactAdapter.add(contacts);

                count++;

                lstv.setText("Available: " + count + " members");
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }


        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id)
            {
                Intent intent = new Intent(getApplicationContext(), SingleUser.class);
                intent.putExtra("username", String.valueOf(listView.getSelectedItem()));
                startActivity(intent);
            }
        });
    }
}

我尝试从这个ListView的数据传递到另一个的EditText在其他
 活动，但结果始终是空，我想通过所有文本
 字符串从ListView控件到的EditText。

I try to pass data from this ListView to another EditText in an other activity but the result is always "null", I want to pass all the text string from the ListView to the EditText.

推荐答案

做到这一点的方式，

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position, long id)
            {
                Intent intent = new Intent(getApplicationContext(), SingleUser.class);
                intent.putExtra("username", YourModels.get(position).getUsername());//here first get position and than pass data you want to pass
                intent.putExtra("fk_Code", "" + YourModels.get(position).getFk_Code());//take data from your model
                startActivity(intent);
            }
        });
