initView
mSearchView = (SearchView) findViewById(R.id.searchView);
lv = (ListView) findViewById(R.id.lv_police);

自定义Adapter 并添加过滤
``` private class MyAdapter extends BaseAdapter implements Filterable {
private MyFilter mFilter;
@Override
public int getCount() {
return mData.size();
}
@Override
public Object getItem(int position) {
return mData.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (null == convertView) {
convertView = View.inflate(PoliceActivity.this,
R.layout.police_item, null);
}
TextView name = (TextView) convertView
.findViewById(R.id.tv_police_name);
TextView duiName = (TextView) convertView
.findViewById(R.id.tv_police_duizhang);
TextView number = (TextView) convertView
.findViewById(R.id.tv_police_number);
name.setText(mData.get(position).getJwsmc());
duiName.setText(mData.get(position).getDzxm());
number.setText(mData.get(position).getPddys() + "");
return convertView;
}
@Override
public Filter getFilter() {
if (null == mFilter) {
mFilter = new MyFilter();
}
return mFilter;
}
// 自定义Filter类
class MyFilter extends Filter {
@Override
// 该方法在子线程中执行
// 自定义过滤规则
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
List<ListBean> newValues = new ArrayList<ListBean>();
String filterString = constraint.toString().trim()
.toLowerCase();
// 如果搜索框内容为空，就恢复原始数据
if (TextUtils.isEmpty(filterString)) {
newValues = mBackData;
} else {
// 过滤出新数据
for (ListBean str : mBackData) {
if (-1 != str.getJwsmc().toLowerCase()
.indexOf(filterString)) {
newValues.add(str);
}
}
}
results.values = newValues;
results.count = newValues.size();
return results;
}
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
mData = (List<ListBean>) results.values;
if (results.count > 0) {
mAdapter.notifyDataSetChanged(); // 通知数据发生了改变
} else {
mAdapter.notifyDataSetInvalidated(); // 通知数据失效
}
}
}
}```
需要重写的两个方法，onQueryTextSubmit 是你点击键盘的搜索二字 会触发的方法 直接return false也行。
onQueryTextChange 你每输入一个字符就会触发一次，也会刷新一次适配器：
``` @Override
public boolean onQueryTextSubmit(String query) {
if (mSearchView != null) {
// 得到输入管理对象
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
// 这将让键盘在所有的情况下都被隐藏
imm.hideSoftInputFromWindow(mSearchView.getWindowToken(), 0); // 输入法如果是显示状态，那么就隐藏输入法
}
mSearchView.clearFocus(); // 不获取焦点
}
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
// TODO Auto-generated method stub
if (TextUtils.isEmpty(newText)) {
// 清楚ListView的过滤
mAdapter.getFilter().filter("");
// lv.clearTextFilter();
} else {
// 使用用户输入的内容对ListView的列表项进行过滤
// 主要是这句写上就没黑框了
mAdapter.getFilter().filter(newText);
// lv.setFilterText(newText);
}
return true;
}```
去除黑色背景
不获取焦点无效
