Android关键字模糊查询，并带有高亮效果
主要功能代码在aftertextchange方法中操作，之前用
SpannableStringBuilder方法会出现错误，不能被序列化，所以只好用html拼接的方法
private TextWatcher mTWatcher = new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void afterTextChanged(Editable s) {
int index;
if(editText.getText().toString().length() > 0){
clearBtn.setVisibility(View.VISIBLE);
wordEdt = editText.getText().toString().trim();
banks.clear();
for(int i = 0;i < branchList.size();i++){
BankBranch bankBranch = branchList.get(i);
bankBranch.setSearchName(null);
String bankName = bankBranch.getName();
// ForegroundColorSpan span = new ForegroundColorSpan(getResources().getColor(R.color.red));//要显示的颜色
// SpannableStringBuilder builder = new SpannableStringBuilder(bankBranch.getName());
index = bankName.indexOf(wordEdt);//从第几个匹配上
if(index != -1){
// builder.setSpan(span, index, index+wordEdt.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
bankBranch.setSearchName(bankName.substring(0,index)+getBankName(wordEdt)+bankName.substring(index+wordEdt.length(), bankName.length()));
banks.add(bankBranch);
}
}

listV.setAdapter(adapter);

adapter.notifyDataSetChanged();

clearBtn.setVisibility(View.INVISIBLE);

颜色设置的方法
/**

* @return
*/
public String getBankName(String name1){
String s1=""+name1+"";
return s1;
}
