我在我的应用程序中使用微调器,所以我需要重置按钮.单击clearButton按钮微调器应该清除(不应显示任何值)

spinner=  (Spinner) view.findViewById(R.id.mylistspinner);

list= new ArrayList<String>();

list.add("");

list.add("1");        
list.add("2");

adapter= new ArrayAdapter<String>(getActivity(),R.layout.custom_spinner_text,list);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(urineGlucoseAdapter);
        spinner.setOnItemSelectedListener(new OnUGItemSelected());

我有一个,ListView并且在其中ListView我有一些TextViews和其中EditTexts的一行.当我按下该行的任何地方时,我希望获得EditText焦点,以便输入文本.

问题是我不能让这个工作.当我放置EditText在ListView了OnItemClick,当我点击不会响应ListView.

我试着用focusable="false"的EditText,它让我点击ListView一次,但我不能让EditText即使是可聚焦设置为true后获得焦点.接下来我尝试使用android:descendantFocusability="beforeDescendants"in ListView但它似乎没有做任何改变,它仍然无法正常工作.

有没有人知道我能做些什么让它起作用？

我希望有人可以帮助我解决这个问题.我无法重现此错误,但收到了大量的崩溃报告.下面是堆栈跟踪和相关代码.我想添加"cursor.close();" 会解决问题,但事实并非如此.任何人都可以弄明白发生了什么？第187行是mDbAdapter.close();
