所以我试图使用自定义数组适配器创建可搜索的列表视图。
我终于让搜索工作了,但结果并不准确。
它实际上是一种打击和错过的有点事情,例如搜索Drupal让我获得Google Plus,你知道我说的是什么?
所以我的适配器
public class CustomListAdapter extends ArrayAdapter<String> implements Filterable {
private final Activity context;
private final String[] web;
private final String[] imageIdUrl;
public CustomListAdapter(Activity context, String[] web, String[] imageId) {
super(context, R.layout.list_single, web);
this.context = context;
this.web = web;
this.imageIdUrl = imageId;
}
@Override
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
//find row view
View rowView= inflater.inflate(R.layout.list_single, null, true);
//find text
TextView txtTitle = (TextView) rowView.findViewById(R.id.txt);
//find image
ImageView imageView = (ImageView) rowView.findViewById(R.id.img);
//set text
txtTitle.setText(web[position]);
//set image traditional
//imageView.setImageResource(imageIdUrl[position]);
//set image with picasso
Picasso.with(this.context).load(imageIdUrl[position]).into(imageView);
//return row
return rowView;
}
}
继承我的主要活动课程
public class MainActivity extends ActionBarActivity {
ListView list;
EditText editsearch;
String[] web = {
"Google Plus",
"Twitter",
"Windows",
"Bing",
"Itunes",
"Wordpress",
"Drupal"} ;
String[] imageIdUrl = {
"http://www.h3dwallpapers.com/wp-content/uploads/2015/05/Google_Logo_04.jpg",
"http://www.h3dwallpapers.com/wp-content/uploads/2015/05/Google_Logo_04.jpg" ,
"http://www.h3dwallpapers.com/wp-content/uploads/2015/05/Google_Logo_04.jpg",
"http://www.h3dwallpapers.com/wp-content/uploads/2015/05/Google_Logo_04.jpg",

"http://www.h3dwallpapers.com/wp-content/uploads/2015/05/Google_Logo_04.jpg"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final CustomListAdapter adapter = new CustomListAdapter(MainActivity.this, web, imageIdUrl);
list=(ListView)findViewById(R.id.list);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(MainActivity.this, "You Clicked at " + web[+position], Toast.LENGTH_SHORT).show();
}
});
// Locate the EditText in listview_main.xml
editsearch = (EditText) findViewById(R.id.editText);
editsearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
String text = editsearch.getText().toString().toLowerCase(Locale.getDefault());
adapter.getFilter().filter(text);
}
@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
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
我会非常感谢任何帮助。这被证明是一个令人头疼的问题
答案 0 :(得分:1)
将onTextChanged()方法中的代码更改为afterTextChanged()方法,如下所示:
Options +FollowSymLinks -MultiViews
RewriteEngine On
# to convert spaces to hyphens
RewriteRule "^(pdf)/(\S*) +(.*)$" /$1/$2-$3 [L,NE,R=302]
RewriteRule ^(pdf/.+)$ /pdf.php?file=$1 [L,QSA,B,NC]
在getSearchItems中正确使用过滤器。我用其他方式过滤为,
@Override
public void afterTextChanged(Editable s) {
String str=s.toString();
getSearchItems(str);
}
然后在适配器中使用另一个方法refresh(),如下所示:
public void getSearchItems(String searchText){
List<Employee> searchList=new ArrayList<Employee>();
List<Employee> employeeList=getEmployeeList();
if(employeeList2!=null){
for(Employee e:employeeList){
if(e.name.toLowerCase().contains(searchText.toLowerCase())){
searchList.add(e);
}
}
}
adapter.refresh(searchList);
}
实际上我使用的Employee类包含他的姓名和地址,我使用员工姓名进行了搜索。所以你改变上面适合你搜索的代码。
