我有一个自定义列表视图行,其中包含许多textView组件。我创建了一个项目,而不是“标准”单个文本项,其中每个listview行包含几个信息位。对于此示例,我有listview中每行的记录ID,名称和描述。
我的listview填充了
this.mDbHelper = new RecordDBAdapter(this);
this.mDbHelper.open();
Cursor c = this.mDbHelper.fetchAllRecords();
startManagingCursor(c);
String[] from = new String[] {RecordDBAdapter.ROW_ID, RecordDBAdapter.NAME, RecordDBAdapter.DESCRIPTION};
int[] to = new int[] {R.id.recordId, R.id.lblName, R.id.lblDescription};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter records = new SimpleCursorAdapter(this, R.layout.record_row, c, from, to);
this.list.setAdapter(dives);
现在我想要的是能够访问每个被点击的项目中的recordId值。我试过按照Android教程无济于事。他们做的事情就像
Object o = adapter.getItemAtPosition(position);
但这仍然无济于事。我真正想要的是获取每个选定listItem的recordId WITHIN的值。有谁知道这将如何实现?这是我的onItemClick事件:
protected OnItemClickListener onListItemClick = new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long rowId) {
// My goal is either to grab the value of the
// recordId value from the textView, or from the adapter.
//Object o = adapter.getItemAtPosition(position); //Tried this, no joy
Intent intent = new Intent(NeatActivity.this, SomeOtherActivity.class);
// intent.putExtra("selectedRecordId",val); //val here is a numerical record row id being passed to another activity.
startActivity(intent);
}
};

你试图从默认的适配器类中做太多。您需要编写自己的适配器类,扩展simplecursoradapter
,然后您可以在任何您想要的位置制作任何您想要的方法。
