Android的列表视图中点击问题 [英] android list view clickable problem

问题描述

我有这个自定义列表。各行包含一个图像和两行下方的其他文本之一。我想开一个新的活动的任何列表项被点击时。但我不能这样做，即使实施setOnItemClickListener后（）。请纠正我，如果我错了。下面是code的名单。 PS：这是一种正常的活动，而不是单活动

  l1.setAdapter（新EfficientAdapter（这一点，eventTitleArray，eventDateArray，eventImageLinkArray））;
   // L1 = getListView（）;
   l1.setClickable（真正的）;
   l1.setOnItemClickListener（新OnItemClickListener（）{
    @覆盖
    公共无效onItemClick（适配器视图＆LT;＆GT;为arg0，查看ARG1，
      INT位置，长ARG3）{
     意向意图=新的意图（MainActivity.this，DisplayActivity.class）;
     叠B =新包（）;
     b.putString（事件，eventTitleArray [位置]）;
     intent.putExtras（包）;
     startActivity（意向）;

     Toast.makeText（getApplicationContext（），打开详细视图：+ eventTitleArray [位置]，Toast.LENGTH_SHORT）.show（）;


    }
   }）;
 

解决方案

请看看行布局是否具有可获得焦点是任何项目。如果ListView项包含可成为焦点的儿童，列表视图处理程序不会被解雇。

i have this customized list. each row contains an image and two lines of text one below the other. i want to open a new activity when any list item is clicked. but i am not able to do so, even after implementing the setOnItemClickListener(). please correct me if i am wrong. the below is the code for the list. PS: This is an normal activity and not list activity.

l1.setAdapter(new EfficientAdapter(this,eventTitleArray,eventDateArray,eventImageLinkArray));
   //l1 = getListView();
   l1.setClickable(true);
   l1.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1,
      int position, long arg3) {
     Intent intent = new Intent(MainActivity.this, DisplayActivity.class);
     Bundle b = new Bundle();
     b.putString("event", eventTitleArray[position]);
     intent.putExtras(bundle);
     startActivity(intent);

     Toast.makeText(getApplicationContext(), "Opening detailed view for:"+eventTitleArray[position], Toast.LENGTH_SHORT).show();


    }
   });

解决方案

Please have a look whether the row layout has any items which are focusable. If an ListView Item contains focusable children, the Listview Handler will not be fired.
