Android .SETONITEMCLICK侦听器不工作

我想借助intent和uri将我的数据从一个活动发送到另一个活动，但任务没有完成

我的主要活动代码

    // Inflate the menu; this adds items to the action bar if it is present.

    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

@Override
public Loader<Cursor> onCreateLoader(int i, Bundle bundle) {
    String[] projection = {
            ItemContract.ItemEntry._ID,
            ItemContract.ItemEntry.NAME,
            ItemContract.ItemEntry.PRICE,
            ItemContract.ItemEntry.QUANTITY,
            };

    // This loader will execute the ContentProvider's query method on a background thread
    return new CursorLoader(this,   // Parent activity context
            ItemContract.ItemEntry.CONTENT_URI,   // Provider content URI to query
            projection,             // Columns to include in the resulting Cursor
            null,                   // No selection clause
            null,                   // No selection arguments
            null);

}

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
    mCursorAdapter.swapCursor(data);

}

@Override
public void onLoaderReset(Loader<Cursor> loader) {
    mCursorAdapter.swapCursor(null);

}

如果我添加了我在适配器类itnet中注释过的意图代码，则会成功执行，但没有数据从列表视图传递到意图

提前谢谢。

有没有SetoniceMcClicklistner？？因为你是setOnclickListner。在Adapterys的打字错误中，我想从主要活动中了解一下是否存在SetonimeClickListner？？因为你是setOnclickListner。在Adapterys的打字错误中，我想从主要活动中删除意图
