如何在listviewOnItemClickListener中gettext??

我无法在 listview toast 中获取文本 work.but gettext(); 不起作用

这是我的代码。提前致谢。

      listView.setOnItemClickListener(new OnItemClickListener() {
        @SuppressWarnings("unused")
        @Override
        public void onItemClick(AdapterView<?> parent, View view, 
            int position, long id) {
          // ListView Clicked item index
          int itemPosition = position;

          //parent.getChildAt(position - listView.getLastVisiblePosition()).findViewById(R.id.listView1);   
          String itemValue = (String) listView.getItemAtPosition(position);

          //???????????????????????????.getText().toString();

          // Show Alert 
          Toast.makeText(
            getApplicationContext(),
            "Position :" + itemPosition + " ListItem: " + itemValue,
            Toast.LENGTH_LONG
          ).show();
        }
      });

Answer 1

You have to get the id of the textView from the view parameter like this

public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {

TextView textView =(TextView) view.findViewById(R.Id.YourTextViewId);
String str=textView.getText();

}

Answer 2

我想你可以试试这个：

@Override
public void onItemClick(AdapterView<?> view, View v, int position, long arg3) {
ListView l = (ListView) view;
String s = (String) l.getItemAtPosition(position);
}

Answer 3

而不是从视图中获取文本。从您用来将数据绑定到 ArrayAdapter.

的数据集 values 中获取

String itemValue = values[position];
Toast.makeText(YourActivty.this, "Clicked " + itemValue + " at " + position, Toast.LENGTH_LONG).show();

Answer 4

只需键入此代码并在您的项目中导入 textview

 String itemValue = (String) listView.getItemAtPosition(position);
 String values=((TextView)view).getText().toString();

Answer 5

试试这个：

lista.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    @Override

     public void onItemClick(AdapterView<?> parent, View view, int position, long      id){

           TextView txt = (TextView) view.findViewById(R.id.lblId);
           String s = textView.getText().toString();
           Toast.makeText(getActivity(), "Your id "+s, Toast.LENGTH_SHORT).show();
    }
});
