onitemclick

如果一个ListView item中，包含了其它可以出发点击事件的widget，例如button , 会发生ListView 无法触发 OnItemClickListener 中的onItemClick点击事件，原因是因为button抢夺了listview 的焦点。 解决方法很简单：在button配置文件中加入属性： android:focusable="false" <Button android:id="@+id/btnBuy" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:background="@drawable/btn_normal" android:layout_marginTop="5dip" android:layout_alignParentBottom="true" android:text="立即抢购" android:focusable="false" android:textColor="@color/white" /> 来源： oschina 链接： https://my.oschina.net/u/259425/blog/54929

当ListView设置了OnItemClickListener, Item项里的View设置了OnClickListener时, 经常遇到某一个Listener失效的现象. 根本原因是焦点的问题, 当item项目中某个View能够获取焦点时, 根据View焦点传递的规则会优先接受点击事件, 如此就会导致ListView的OnItemClickListener失效. 因为能够自动获取焦点的View有优先获取点击事件的权利, OnItemClickListener是在Item的父节点, 所以它是最后一个处理点击事件的(虽然最先接收, 但是先分发给子View, 子View处理完后, 最后自己处理). 如果子View处理并消化了点击事件, 那么OnItemClickListener久失效了. 解决的方法: 1 你可以放弃 OnItemClickListener, 只是用 OnClickListener. 2 检查你的Item 里, 时候有focusable=true 和 focusableInTouchMode=true的View. 如果有, 把他们都设置成false. 来源： oschina 链接： https://my.oschina.net/u/1393188/blog/518080

My app implements a HashMap , such that when a key is typed in the AutoCompleteTextView editText , and user clicks a dropdown item, the value gets displayed on a textView . The only problem is that the clicked drop-down item does not respond on the first click (this only happens once, after the app is launched but works fine subsequently), the user MUST re-type a key and click the item before it displays the value. Any suggestions as to how to resolve this? Java code: public class MainActivity extends ActionBarActivity { Map<String, String> map = new HashMap<String, String>(); private EditText

I try to get the value of a selected Item within a custom adapter on a listview. I try this with following code: public void onItemClick(AdapterView<?> parent, View v, int position, long id) { View curr = parent.getChildAt((int) id); TextView c = (TextView)curr.findViewById(R.id.tvPopUpItem); String playerChanged = c.getText().toString(); Toast.makeText(Settings.this,playerChanged, Toast.LENGTH_SHORT).show(); } At the beginning, if I click, the values are good, but once I scrolled and I click on another Item, I get the wrong value of that clicked item... Any idea what is causing this? The

I am trying to implement my own recyclerview Animation - I would like to achieve this without using any external libraries. Here is what the theoretical animation should look like. The user clicks an item on the List and an animation occurs which opens up another View. On a high level with minimal code, possibly just pseudo code what would the process be in order to create some animation like that? Also I would like to note that the animation should be able to be done in reverse as well if the user clicks the same item or another item I am not that familiar with the RecyclerView class and

The below is my testing code to create the list view, the list view display successfully, however, there is error in click event. I would like to create an intent to send a hardcode message to an new activity. However, it show error for the line Intent intent = new Intent(context, SendMessage.class); So , the problem is , what should I provide for this class? Also , instead of hard code the output message, how to capture the data in list view row and pass to the new activity? e.g. BBB,AAA,R.drawable.tab1_hdpi for the first row.
