我正在开发一种墙纸应用程序,该应用程序可从Picasa加载其图像。我有一个导航抽屉,可从Picasa相册名称中检索其商品名称(我正在使用本教程的源代码链接 ),所以我想添加一个用于过滤的搜索栏导航抽屉中的项目,关于如何完成此操作的任何想法?
It might be a little late. But may help others.
Add an EditText to navigation Drawer.(activity_main.xml)
<EditText android:id="@+id/inputSearch" android:layout_width="match_parent" android:layout_height="40dp" android:layout_margin="10dp" android:hint="search" android:padding="10dp" android:layout_marginTop="25dp" android:inputType="text" > </EditText>
add a TextWatcher to editText. (Add the following lines to onCreate
)
final EditText inputSearch = (EditText) findViewById(R.id.inputSearch); inputSearch.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub //You should use the adapter in NavigationDrawerFragment NavigationDrawerFragment.adapter.getFilter().filter(cs); } @Override public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable arg0) { // TODO Auto-generated method stub } });
Hope this helps.
You can make your navigation drawer a Fragment
that contains an ArrayAdapter
, which implements Filterable
. This adapter would contain list of your Picasa album names.
For the search box, a simple EditText
would do the job. Register a TextWatcher
that would listen to text change events and trigger Filter.filter()
on a Filter
returned from your ArrayAdapter.getFilter()
with input text as query.
