我有什么: 我在列表视图的每一行都有文本视图
我要做的是:
CODE ::
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listviewdemo);
final ListView listviewone = (ListView) findViewById(R.id.listviewone);
listviewone.setAdapter(mAdapterOne);
listviewone.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
Log.d("", "");
}
});
}
适配器的XML
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#fff"
android:orientation="vertical" >
<TextView
android:id="@+id/title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:textColor="#000" />
<ImageView
android:id="@+id/image"
android:layout_width="150dp"
android:layout_height="150dp"
android:scaleType="centerCrop"
android:padding="5dp"
android:src="@drawable/img" />
<ImageView
android:id="@+id/imageLine"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/line" />
</LinearLayout>

view是列表项,因此您可以执行
String str =(String) ((TextView) view.findViewById(R.id.txt)).getText();
答案 1 :(得分:1)
((TextView) view.findViewById(R.id.title).getText().toString()
但是我建议你从适配器本身获取文本,因为适配器将用于填充ListView。

如果你想在textview上设置值,那就试试吧..
listviewone.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
TextView mText = (TextView) view
.findViewById(R.id.title);
String value= mText.getText().ToString().trim();
}
});

从ListView数据持有者处获取特定列表项的名称:
示例:
ArrayList<HashMap<String,String>> listData= new ArrayList<HashMap<String, String>>();
HashMap<String,String> row1= new HashMap<String, String>();
row1.put("name","AAA");
listData.add(row1);
listviewone.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
Log.d("Name :", listData.get(position).get("name"));
}
});
注意: listData用于ListView数据持有者,它是传递适配器以构建ListView项目。

尝试这样,
private String getName(int pos){
View view = listviewone.getAdapter().getView(pos, null, listviewone);
TextView name = (TextView) view.findViewById(R.id.title);
return name.getText().ToString();
}
listviewone.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
Log.d("NAME", getName(position));
}
});
希望它会帮助你

在interface
上使用TextView
点击活动
代码段
用于处理点击事件的接口
public interface ListItemBtnClickInterface {
public void listItemBtnClickListener(Object obj, int viewId, String value);
}
我正在使用ArrayAdapter
适配器 的构造函数的代码
public AddExpTypeAdapter(Context context, int resource,
List<ExpenseTypeInfo> objects, ListItemBtnClickInterface _interface) {
super(context, resource, objects);
// TODO Auto-generated constructor stub
_context = context;
layoutId = resource;
dataList = objects;
this._interface = _interface;
notifyDataSetChanged();
}
初始化并设置文本后, 适配器中的 TextView点击的代码
vieweHolder.urView.setTag(position);
vieweHolder.urView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Object data = v.getTag();
if(data != null) {
String value = vieweHolder.urView.getText().toString();
_interface.listItemBtnClickListener(data, v.getId(), value);
}
}
});
ListView
中Activity
的设置适配器的代码
addExpTypeAdapter = new AddExpTypeAdapter(AddExpTypeActivity.this,
R.layout.row_add_type, expTypeList, new ListItemBtnClickInterface() {
private int clickedPosition;
@Override
public void listItemBtnClickListener(Object obj, int viewId, String value) {
// TODO Auto-generated method stub
clickedPosition = Integer.parseInt(obj.toString());
switch (viewId) {
case R.id.urView:
Log.d("Clicked TextView's Value ===> " , value);
break;
default:
break;
}
}
});
typeListView.setAdapter(addExpTypeAdapter);
