效果



代码已上传至github

项目里要做一个对列表内容的筛选，想到了知乎以及google play的效果，确定了是用Toolbar、SearchView、RecyclerView实现

Toolbar不用多说，如有不懂我也上传到了github 
Recycler我之前也写过Demo，同样上传到了github 
难搞的是SearchView，毕竟现在都流行Material Design了嘛，自带的那个效果实在不敢恭维，网上搜了下，已有大神实现了MaterialDesign效果的SearchView，所以拿来用咯

部分代码，我贴一下，详情请看Demo

初始化操作

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

ButterKnife.bind(this);

initView();
}

private void initView() {

initToolBar();
initRecyclerView();
initSearchView();

}

/**
* init Toolbar
*/
private void initToolBar() {
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
}

/**
* init RecyclerView
*/
private void initRecyclerView() {

LinearLayoutManager layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);

mPeopleList = new ArrayList<>();

String[] peopleName = {"Kaka", "Modric", "Rooney", "Ibla", "Bale", "死神", "Maurice Moss", "Roy Trenneman", "林夕", "sina", "google", "ecust"};
String[] peopleDes = {"The best player", "莫德里奇是最好的后腰", "鲁尼踢得不好", "伊贝拉是谁？", "贝尔跑得真快", "Aaron", "Oh, four, I mean five, I mean fire!", "哈哈", "是个艺术家", "weibo", "android", "china"};

for (int i = 0; i < peopleName.length; i++) {
mPeopleList.add(new People(peopleName[i], peopleDes[i]));
}

mAdapter = new SearchPeopleAdapter(mPeopleList);
recyclerView.setAdapter(mAdapter);
HeaderAdapter headerAdapter = new HeaderAdapter(mAdapter);

recyclerView.setAdapter(headerAdapter);
recyclerView.addOnItemTouchListener(new RecyclerOnItemClickListener(this, recyclerView, this));

}

/**
* init SearchView
*/
private void initSearchView() {

searchView.setVoiceSearch(false);
searchView.setCursorDrawable(R.drawable.custom_cursor);
searchView.setEllipsize(true);
searchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {

return true;
}

@Override
public boolean onQueryTextChange(String newText) {
final List<People> filteredModelList = filter(mPeopleList, newText);

//reset
mAdapter.setFilter(filteredModelList);
mAdapter.animateTo(filteredModelList);
recyclerView.scrollToPosition(0);
return true;
}
});

searchView.setOnSearchViewListener(new MaterialSearchView.SearchViewListener() {
@Override
public void onSearchViewShown() {
}

@Override
public void onSearchViewClosed() {
mAdapter.setFilter(mPeopleList);
}
});

}

/**
* 搜索按钮
*
* @param menu
* @return
*/
@Override
public boolean onCreateOptionsMenu(Menu menu) {

getMenuInflater().inflate(R.menu.menu_search, menu);
MenuItem item = menu.findItem(R.id.action_search);
searchView.setMenuItem(item);

return true;
}
