单击按钮单击列表视图时获取值

Question

    public class CustomList extends ArrayAdapter<String> {

            private final Activity context;
            private final ArrayList<String> web;
         public CustomList(Activity context, ArrayList<String> web ) {
                super(context, R.layout.list_single,web);
                this.context = context;
                this.web = web;
         }

            @Override
            public View getView(int position, View view, ViewGroup parent) {
                LayoutInflater inflater = context.getLayoutInflater();
                View rowView = inflater.inflate(R.layout.list_single, null, true);
                EditText txtTitle = (EditText) rowView.findViewById(R.id.txt);
  Button btn=(Button)rowView.findViewById(R.id.btn);

                ImageView imageView = (ImageView) rowView.findViewById(R.id.img);
                txtTitle.setText(web.get(position));
        return rowView;
            }
        }

    public class MainActivity extends Activity {
        ListView list;
        ArrayList<String> web = new ArrayList<String>();
           @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            web.add("Dsfsaf");
            web.add("xcxc");
            web.add("Dsfsafxcxc");



            CustomList adapter = new CustomList(MainActivity.this, web);
            list = (ListView) findViewById(R.id.list);
            list.setAdapter(adapter);
          }
      }

在上面的示例中，我使用自定义适配器显示列表视图，包括文本视图，TextField和Button。它工作正常，但我需要在单击按钮时获取输入文本字段值

使用OnItemClickListener！ 像这样实现：onItemClick (AdapterView<?> parent, View view, int position, long id) 您的“view”参数将是您的行布局。然后就像这样得到你的编辑文本：

EditText txtTitle = (EditText) view.findViewById(R.id.txt);

然后以通常的方式使用你的字符串：

String yourString = txtTitle.getText().toString();
