java获取listview外部的edittext值，获取OnItemClick内部的edittext值

Question

我是安卓应用开发新手

我想获取listview外部的edittext值，我想获取OnItemClick内部的值。当用户输入文本并单击列表项时，我需要同时获取列表项和编辑文本值

我创建了包含一个edittext和listview的主布局。我想在listview和McClick事件中获取edittext值

我试过了，但没办法。请引导我

这里我列出了我的示例程序

import java.util.ArrayList;

import 安卓.app.Activity;
import 安卓.os.Bundle;
import 安卓.widget.EditText;
import 安卓.widget.ListView;

public class MainActivity extends Activity {
    ArrayList<String> listVal = new ArrayList<String>();
    public EditText searchKey;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        searchKey = (EditText) findViewById(R.id.searchKey);
        ListView spinner = (ListView) findViewById(R.id.listView1);
        listVal.add("Apple");
        listVal.add("Avocado");
        listVal.add("Banana");
        listVal.add("Blueberry");
        listVal.add("Coconut");
        listVal.add("Durian");
        listVal.add("Guava");
        listVal.add("Kiwifruit");
        listVal.add("Jackfruit");
        ListAdapter listAdapter = new ListAdapter(getApplicationContext(), R.layout.list, listVal);
        spinner.setAdapter(listAdapter);
        spinner.setOnItemClickListener(listAdapter);
    }
}

ListAdapter。爪哇

public class ListAdapter extends ArrayAdapter<String> implements OnItemClickListener {

    private final Context context;
    private final ArrayList<String> values;
    int layoutResourceId;
    public ListAdapter(Context context, int layoutResourceId, ArrayList<String> values) {
        super(context, layoutResourceId, values);
        this.context = context;
        this.layoutResourceId = layoutResourceId;
        this.values = values;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View rowView = inflater.inflate(layoutResourceId, parent, false);
            TextView textView = (TextView) rowView.findViewById(R.id.listItem);
            textView.setText(values.get(position));
            return rowView;
    }

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        TextView message = (TextView)arg1.findViewById(R.id.listItem);
        Toast.makeText(context, message.getText().toString(), Toast.LENGTH_SHORT).show();
    }

Answer 1

试试这个

        public class MainActivity extends Activity {
            ArrayList<String> listVal = new ArrayList<String>();
            public EditText searchKey;
            @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);
                searchKey = (EditText) findViewById(R.id.searchKey);
                ListView spinner = (ListView) findViewById(R.id.listView1);
                listVal.add("Apple");
                listVal.add("Avocado");
                listVal.add("Banana");
                listVal.add("Blueberry");
                listVal.add("Coconut");
                listVal.add("Durian");
                listVal.add("Guava");
                listVal.add("Kiwifruit");
                listVal.add("Jackfruit");
                ListAdapter listAdapter = new ListAdapter(getApplicationContext(), R.layout.list, listVal);
                spinner.setAdapter(listAdapter);
                spinner.setOnItemClickListener(new OnItemClickListener()
                {
                    @Override
                    public void onItemClick(AdapterView<?> arg0, View v, int pos,
                            long id) {
                        // TODO Auto-generated method stub
                        Log.v("listitem_value",values.get(pos));
                        Log.v("EditTextValue",searchKey.getText().toString().trim());
                        Toast.makeText(context, "listitem_value:"+values.get(pos)+"\nEditTextValue:"+searchKey.getText().toString().trim(), Toast.LENGTH_SHORT).show();
                    }
                });
            }

    }

并在ListAdapter中删除implements OnItemClickListener和onItemClick方法

     spinner.setOnItemClickListener(new OnItemClickListener()
        {
            @Override
            public void onItemClick(AdapterView<?> arg0, View v, int pos,
                    long id) {
                // TODO Auto-generated method stub
               TextView message = (TextView)arg1.findViewById(R.id.listItem);
               Toast.makeText(context, message.getText().toString(),    Toast.LENGTH_SHORT).show();
                           Log.v("EditText",searchKey.getText().toString().trim());
            }
        });
