Question

以下是我的代码：

public class TestActivity extends ListActivity {

    private Cursor cursor;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test);

        fillData(); 
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        // Get the item that was clicked
        Object o = this.getListAdapter().getItem(position);
        String keyword = o.toString();
        Toast.makeText(this, "You selected: " + keyword, Toast.LENGTH_LONG)
                .show();
    }

    private void fillData() {
        TermsData_DataHelper termsDataHelper = new TermsData_DataHelper(
                TestActivity.this);
        cursor = termsDataHelper.fetchAllCategories();
        startManagingCursor(cursor);

        String[] names = new String[] { "name" };
        int[] to = new int[] { R.id.label };

        // Now create an array adapter and set it to display using our row
        SimpleCursorAdapter categories = new SimpleCursorAdapter(this,
                R.layout.terms_row, cursor, names, to);
        setListAdapter(categories);
    }
}

当我点击列表视图中的一行时，我看不到任何Toast。任何人都可以告诉我我在哪里犯了错误。

提前致谢。

Answer 1

我遇到了类似的问题，发现从我的列表项中删除android:clickable="true"后，onListItemClick（）被触发就好了。我希望这会有所帮助。

Answer 2

protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);

    String mString = parent.getItemAtPosition(position).toString();
    //will give you the text of current line or
    int i = parent.getItemAtPosition(position);
    //if you want just position number
}

Answer 3

解决方案是覆盖protected void onListItemClick (ListView l, View v, int position, long id)方法。

Answer 4

我也有这个问题。我通过在布局XML中从TextView中删除它来解决它。

    android:textIsSelectable="true"

Android：Listview的onItemClick（）事件未被调用
