【中文标题】过滤器搜索后列表视图中的复选框更改位置【英文标题】：Checkbox in listview changes position after filter search 【发布时间】：2015-09-23 11:35:14 【问题描述】：我的checkbox在过滤器搜索后改变了位置，我不明白为什么
我将在过滤后的列表中再检查一项：
现在我将清除过滤器，结果将是这样的：
过滤器和checkbox 工作正常，只有当我过滤结果并单击checkbox 时它仍然在顶部？？
这是我的代码：
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.choosegroup);
getAllContacts(this.getContentResolver());
friends = (ListView) findViewById(R.id.listView);
ma = new MyAdapter();
friends.setAdapter(ma);
friends.setOnItemClickListener(this);
friends.setItemsCanFocus(false);
friends.setTextFilterEnabled(true);
// adding
toolbar = (Toolbar) findViewById(R.id.tool_bar4);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Intent i = getIntent();
groupname = i.getStringExtra("name");
search = (EditText) findViewById(R.id.editText12);
but = (Button) toolbar.findViewById(R.id.buttonz);
but.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
StringBuilder checkedcontacts = new StringBuilder();
System.out.println("..." + ma.mCheckStates.size());
for (int i = 0; i < phno1.size(); i++)
if (ma.mCheckStates.get(i) == true)
checkedcontacts.append(phno1.get(i).toString());
checkedcontacts.append("\n");
else
// System.out.println("Not Checked.." + phno1.get(i).toString());
Toast.makeText(Choosegroup.this, checkedcontacts, Toast.LENGTH_LONG).show();
);
friends.setEmptyView(findViewById(R.id.emptyElement5));
friends.setOnTouchListener(new View.OnTouchListener()
@Override
public boolean onTouch(View v, MotionEvent event)
int action = event.getAction();
switch (action)
case MotionEvent.ACTION_DOWN:
// Disallow ScrollView to intercept touch events.
v.getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_UP:
// Allow ScrollView to intercept touch events.
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
return false;
);
search.addTextChangedListener(new TextWatcher()
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3)
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3)
@Override
public void afterTextChanged(Editable s)
Log.d("tag", "*** Search value changed: " + s.toString());
ma.getFilter().filter(s.toString());
ma.notifyDataSetChanged();
);
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
// TODO Auto-generated method stub
ma.toggle(arg2);
