我无法收到 Toast 消息,因为从未调用过onItemClick。Log-cat 没有显示任何错误。如果我在任何地方出错,请检查我的代码并纠正我。我用过阵列适配器。

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"
     />

我遇到了类似的问题。不仅我的 onItemClick 方法被忽略,而且我的列表选择器也不起作用(android:listSelector。)

原来它是android:textIsSelectable我的 TextView 行元素上的属性。尝试将其设置为false.

就我而言,问题出在android:longClickable="true". 从 xml 中删除此行后,单击侦听器再次开始工作。
