Question

我尝试在列表视图中实现longClick但是我只在编辑文本字段中获得longClick：如何只在textView上获取longClick？

谢谢Daniele

其他细节：

主要布局是“activity_main.xml”，在列表视图“listView_listData”中，我将“row.xml”布局与“RigaAdvAdapter”类放在一起;
布局“row.xml”有两个字段：textView和editText;
我使用ArrayList来存储我想要在行中查看的数据（以逗号分隔 - 例如“viewTextValue，editTextValue”）;
我需要在每行中获取longClick以提供更多选项;
我不需要在editText中使用longClick，否则复制粘贴不起作用;
将来我需要更多数据，因此我将使用ArrayList数组;

            android:inputType="text">
            <requestFocus />
        </EditText>
    </TableRow>
</TableLayout>

MainActivity

public class MainActivity extends Activity
    {
    ArrayList<String> arrayDataSource= new ArrayList<String>();

    ...
    I fill the array "arrayDataSource" with a string as "text,another text"
    ...

    @Override
    protected void onCreate(Bundle savedInstanceState)
        {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ListView listView_listData  =(ListView)findViewById(R.id.listView_listData);
        listView_listData.setAdapter(new RigaAdvAdapter());

        listView_listData.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener()
            {
            @Override
            public boolean onItemLongClick(AdapterView<?> arg0, View arg1,int pos, long arg3)
                {
                mostraToast("hh long click"+String.valueOf(pos));
                return true;
                }
            });
        }

适配器类

    public class RigaAdvAdapter extends BaseAdapter
        {
        @Override
        public int getCount() {return arrayDataSource.size();}
        @Override
        public Object getItem(int position) {return position;}
        @Override
        public long getItemId(int position) {return position;}
        @Override
        public View getView(int position, View convertView, ViewGroup parent)
            {
            if (convertView == null)
                {
                LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                convertView = inflater.inflate(R.layout.row, null);
                }

            TextView textViewField = (TextView)convertView.findViewById(R.id.textViewField);
            EditText editTextField = (EditText)convertView.findViewById(R.id.editTextField);

            String StringData=arrayDataSource.get(position);
            String[] ArrayStringData=StringData.split(",",-1);

            String textViewField_val=ArrayStringData[0];
            String editTextField_val=ArrayStringData[1];
            textViewField.setText(textViewField_val);
            editTextField.setText(editTextField_val);

            return convertView;
            }
        }

Answer 1

不必将longclick设置为ListView，而是必须为TextView设置它。在RigaAdvAdapter类中，您必须添加此

  textViewField.setOnLongClickListener(new OnLongClickListener() {

        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            return false;
        }
    });

Answer 2

尝试将edittext属性设置为clickable并将focusable设置为false。正如您已添加Editttext所以它将始终获得第一个焦点和触摸事件。

要在TextView上添加Longclick事件，您必须在适配器类中实现longclick侦听器。

     @Override
    public View getView(int position, View convertView, ViewGroup parent)
        {
        if (convertView == null)
            {
            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.row, null);
            }

        TextView textViewField = (TextView)convertView.findViewById(R.id.textViewField);
        EditText editTextField = (EditText)convertView.findViewById(R.id.editTextField);

    textViewField.setOnLongClickListener(new OnLongClickListener() {

       @Override
        public boolean onLongClick(View v) {
        // TODO Auto-generated method stub
            return false;
        }
     });
        String StringData=arrayDataSource.get(position);
        String[] ArrayStringData=StringData.split(",",-1);

        String textViewField_val=ArrayStringData[0];
        String editTextField_val=ArrayStringData[1];
        textViewField.setText(textViewField_val);
        editTextField.setText(editTextField_val);

        return convertView;
        }

您应该在适配器的getView方法中使用onItemLongClickListener。这个问题可以帮助Android : How to set onClick event for Button in List item of ListView
