我知道这个问题很久远,但今天我也需要这个函数。因为我找不到任何东西,所以我自己为那些微调器做了一个适配器。
适配器:
public class Searchspinner extends ArrayAdapter<String> {
private LayoutInflater inflater;
private boolean dropdown = false;
private OnClickListener onsearch;
private ActionBar ab;
private final ArrayList<String> result = new ArrayList<String>();
private InputMethodManager keyboard;
private boolean searching = false;
public Searchspinner(Context context, int resource,
ArrayList<String> objects, LayoutInflater l, ActionBar a,
InputMethodManager imm, String spinnerid) {
super(context, resource, objects);
inflater = l;
ab = a;
keyboard = imm;
createSearch();
}
@Override
public View getDropDownView(int position, View cnvtView, ViewGroup prnt{
dropdown = true;
return getCustomView(position, cnvtView, prnt);
}
@Override
public View getView(int pos, View cnvtView, ViewGroup prnt) {
dropdown = false;
return getCustomView(pos, cnvtView, prnt);
}
public View getCustomView(int position, View convertView, ViewGroup parent) {
if (!dropdown) {
View mySpinner = inflater.inflate(
R.layout.spinner_ressource_search, parent, false);
TextView main_text = (TextView) mySpinner
.findViewById(R.id.tv_spinner_first);
main_text.setText(getItem(position));
ImageButton search = (ImageButton) mySpinner
.findViewById(R.id.searchbutton);
if (!searching) {
search.setImageResource(R.drawable.search);
} else {
search.setImageResource(R.drawable.search_check);
}
search.setOnClickListener(onsearch);
return mySpinner;
}
View mySpinner = inflater.inflate(R.layout.auftragtextview, parent,
false);
TextView sub_text = (TextView) mySpinner.findViewById(R.id.TextView01);
sub_text.setText(getItem(position));
return mySpinner;
}
private void createSearch() {
onsearch = new OnClickListener() {
@Override
public void onClick(View v) {
if (searching) {
searching = false;
ab.setCustomView(R.layout.actionbar_layout);
ab.getCustomView().setTag("0");
keyboard.toggleSoftInput(0,
InputMethodManager.HIDE_IMPLICIT_ONLY);
for (int i = 0; i < result.size(); i++) {
add(result.get(i));
result.remove(i);
i--;
}
((ImageButton) v).setImageResource(R.drawable.search);
return;
}
((ImageButton) v).setImageResouce(R.drawable.search_check);
searching = true;
ab.setCustomView(R.layout.searchable);
final EditText et = (EditText) ab.getCustomView()
.findViewById(R.id.editText1);
et.setActivated(true);
keyboard.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT,
0);
et.requestFocus();
et.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start,
int before, int count) {
for (int i = 0; i < getCount(); i++) {
if (!getItem(i).contains(s)) {
result.add(getItem(i));
remove(getItem(i));
i--;
}
}
for (int i = 0; i < result.size(); i++) {
if (result.get(i).toLowerCase()
.contains(s.toString().toLowerCase())) {
add(result.get(i));
result.remove(i);
i--;
}
}
}
@Override
public void beforeTextChanged(CharSequence s,
int start, int count, int after) {
}
@Override
public void afterTextChanged(Editable s) {
}
});
}
};
}
}
spinner_ressource_search.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="@+id/tv_spinner_first"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="TextView" />
<ImageButton
android:id="@+id/searchbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="@android:color/transparent"
android:src="@drawable/search" />
</RelativeLayout>
以及auftragtextview.xml文件:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/TextView01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="@+d/TextView01"
android:textSize="16sp" >
</TextView>
以下是创建适配器的方法:
Searchspinner auftragSpinnerAdapter = new Searchspinner(
this.getApplicationContext(),
R.layout.auftragtextview,
list_auftragSpinner,getLayoutInflater(),
getActionBar(),
(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)
);
我希望这能对任何人有所帮助,而且我没有漏掉已经内置的做法:D
问候
编辑:
searcheble.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/actionbar_background_beosys" >
<EditText
android:id="@+id/editText1"
android:hint="@string/suche"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:layout_marginLeft="15dp"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:layout_marginRight="15dp"
android:singleLine="true"
/>
EditText1 就是当你搜索时在视图中显示的简单的 EditText。
ActionbarLayout 是普通的 ActionbarView。
