如何在导航抽屉中添加功能搜索栏？

Question

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？

Answer 1

It might be a little late. But may help others.

1. 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> 

2. 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.
