onItemClick in ListView 不起作用

Question

我无法获得Toast消息，因为onItemClick从未被调用。Log-cat没有显示任何错误。请检查我的代码和纠正我，如果我错了任何地方。我使用了数组适配器。

public class Open extends ListActivity {
    DbAdapter mDb = new DbAdapter(this);
    @Override
    protected void onDestroy() {
        // TODO Auto-generated method stub
        mDb.close();
        super.onDestroy();
    }
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.open);
        ListView listContent = (ListView) findViewById(android.R.id.list);
        mDb.open();
        Cursor cursor =mDb.fetchAllPrograms();
        startManagingCursor(cursor);
        String[] from = new String[] { DbAdapter.KEY_TITLE };
        int[] to = new int[] { R.id.textViewName };
        SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, 
    R.layout.row, cursor, from, to);
        listContent.setAdapter(cursorAdapter);
        //Onclick ListView setlistener
        listContent.setTextFilterEnabled(true);
        listContent=getListView();

            listContent.setOnItemClickListener(new OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View 
    view,int position, long id) {
                    Toast.makeText(getApplicationContext(),
   "Working!", 
                    Toast.LENGTH_LONG).show();    
                }
            });
    }
}

Row.xml如下:

<?xml version="1.0" encoding="utf-8"?>
<TextView
    android:id="@+id/textViewName"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_marginTop="10dp"
     android:layout_marginBottom="10dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="25sp"
    android:textColor="#0000FF"
    android:textIsSelectable="true"
     />

Answer 1

我遇到了一个类似的问题。不仅是我的onItemClick方法被忽略，而且我的列表选择器不工作(android:listSelector .)

原来它是我的TextView行元素的android:textIsSelectable属性。尝试设置为false

Answer 2

在我的情况下，问题是在android:longClickable="true"。从xml中删除这一行后，单击侦听器又开始工作了。
