android - 在 ListView 上长按停止单击操作

Question

我已经通读了 ListView 的所有 longclick + click 监听器 SO 帖子，但找不到解决此问题的方法。根据我读过的帖子，我确信我正在做正确的事情。

问题

我的点击手势用于注册，但在将 LongClickListener 附加到我的 ListView 后，只有长按手势在 ListView 中注册。对我所做的有什么想法吗？

代码

TheStreamActivity.java ( ListView )

public class TheStreamActivity extends AppCompatActivity{
private ListView listView;

/** UI Actions and Set up */
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_the_stream);

    // Attach the adapter to a ListView
    listView = (ListView) findViewById(R.id.stream_feed);

    if (savedInstanceState!=null && !savedInstanceState.isEmpty())
    {
        lvContent = savedInstanceState.getParcelableArrayList(RESTORED_USER_FLOWS);
        manager = savedInstanceState.getParcelable(RESTORED_MANAGER_UTIL);
    } else {
        lvContent = new ArrayList<>();
        manager = new DataManagerUtil(this);
    }


}


/** Sets up each of the individual list view items to be clicked and launch an
 *  new activity based on selected Flow Object.
 *
 */
private void setItemOnClicks() {
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                /* Passes Flow but passes the memory address of the childFlowElements
                 instead of the actual object containing the
                  */
            Flow selectedFlow = (Flow) listView.getItemAtPosition(position);

            Intent i = new Intent(TheStreamActivity.this, FlowSandBoxActivity.class);

            i.putExtra("selectedFlow", selectedFlow);
                // Parcels the Flow Object to@ be passed to new activity
            startActivity(i);
        }

    });

    listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
            showPopUpMenu(TheStreamActivity.this, view);
            return true;
        }
    });
}

public void showPopUpMenu(Context ctx, View v) {
    PopupMenu popup = new PopupMenu(ctx, v);

    // This activity implements OnMenuItemClickListener
    popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem item) {
            switch (item.getItemId())
            {
                case R.id.menu_delete:
                    return true;
                default:
                    return false;
            }

        }
    });
    popup.inflate(R.menu.menu_flow_popup);
    popup.show();
}

@Override
protected void onResume() {
    super.onResume();
    setItemOnClicks();
}

Answer 1

更改 onItemLongClick 方法以返回 false 而不是 true 并且通过这样做你会告诉 android 你希望事件仍然是由其他听众处理。

它应该是这样的:

listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
    @Override
    public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
        showPopUpMenu(TheStreamActivity.this, view);
        return false;
    }
});
