Question

我的项目中有ListView，ListItems就像这样的字符串形式

今天完成任务
将项目分配给开发人员
会议取消

如果单击ListView中的任何一个项目意味着我希望特定的字符串应该显示在我的EditText中（i，如果单击会议取消，我需要在EditText中显示此特定字符串）。任何人指导我，这我是如何尝试Achieve.enter代码在此提前感谢。

final ListView listView =（ListView）findViewById（R.id.taskListDesc）; listView.setOnItemClickListener（new AdapterView.OnItemClickListener（）{

        @Override
        public void onItemClick(AdapterView<?> adapter, View view, int selectedItem,
                long arg3) {

            System.out.println(adapter.getItemAtPosition(selectedItem));

            Intent intent = new Intent(getApplicationContext(),
                    ViewTaskActivity.class);
            startActivity(intent);
        }
    });
}

Answer 1

ArrayAdapter<String> adapter;

adapter=new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item, profielNames); 
setListAdapter(adapter);

 @Override
 protected void onListItemClick(ListView l, View v, int position, long id) {

  super.onListItemClick(l, v, position, id);

  // Get the data associated with selected item
  Object item = l.getItemAtPosition(position);
  String myitem = item.toString();
  edittxt.setText("Selected item is :"+ myitem); // You can Set EditText from Here.
 }

你甚至可以试试这个......

public class ExampleActivity extends Activity {

String str_arr[] = {"A", "B", "C"};


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ListView listView = (ListView) findViewById(R.id.listView1);

    listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, str_arr));

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> adapter, View view, int position,
                long id) {
            // TODO Auto-generated method stub
            Object o = adapter.getItemAtPosition(position);
            String str_text = o.toString();

            Intent intent = new Intent(ExampleActivity.this, NewExample.class);
            intent.putExtra("StrValue", str_text);
            startActivity(intent);
        }

    });
 }
 }

public class NewExample extends Activity {

EditText editText;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.newmain);

    editText = (EditText) findViewById(R.id.editText1);

    String value = getIntent().getStringExtra("StrValue").toString();

    editText.setText(value);
}

}

希望这有助于.......
