APP必备的搜索功能基础源码
可能在很多人看来，搜索是个不起眼的小功能，无需花太多时间赘述。但实际上搜索作为一个app的最基础的功能，如果做的不好很容易直接拉低用户的好感度，特别是对于工具类的app来说，这些必须的功能虽然很难做出彩，但一定不能拉胯。
今天小编就来和大家分享一下搜索功能的基础源码，帮助大家快速上手。
顶部SPSearchView
public class SPSearchView extends LinearLayout {
private ImageView backImgv;
private EditText searchEdtv;
private SPSearchViewListener searchListener;
private SPSearchViewListener searchListener;
/**
* @param context
* @param attrs
*/
public SPSearchView(Context context, AttributeSet attrs) {
super(context, attrs);
View view = LayoutInflater.from(context).inflate(http://doc.docsou.comyout.search_heard_view, this);
searchEdtv = (EditText)view.findViewById(R.id.search_edtv);
backImgv = (ImageView)view.findViewById(R.id.back_imgv);
searchEdtv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (searchListener != null) {
//searchListener.onSearchBoxClick(searchEdtv.getText().toString());
}
}
});
backImgv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (searchListener != null) searchListener.onBackClick();
}
});
searchEdtv.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) { //响应键盘"搜索"键 if (actionId == EditorInfo.IME_ACTION_SEARCH) {
notifyStartSearching(textView.getText().toString());
}
return true;
}
});
}
/**
* 通知监听者进⾏搜索操作
* @param text
*/
private void notifyStartSearching(String text){
if (searchListener != null) {
searchListener.onSearchBoxClick(text);
}
}
public void setSearchKey(String searchKey){
if (this.searchEdtv!=null && !SPStringUtils.isEmpty(searchKey)){
this.searchEdtv.setText(searchKey);
}
}
public EditText getSearchEditText(){
return this.searchEdtv;
}
public void setSearchViewListener(SPSearchViewListener listener){
this.searchListener = listener;
}
public interface SPSearchViewListener{
public void onBackClick();
public void onSearchBoxClick(String keyword);
public void onSearchBoxClick(String keyword);
}
}
搜索界⾯Activity的实现:
布局⽂件:
android:layout_width="match_parent"
android:layout_height="match_parent">
android:id="@+id/search_view"
android:layout_width="match_parent"
android:layout_height="50dip" />
android:id="@+id/search_key_listv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@color/separator_line"
android:dividerHeight="1px"
android:fadingEdge="none"
android:fastScrollEnabled="false"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false"
android:layout_marginTop="50dip"
android:layout_marginBottom="50dip"
android:scrollbars="none"
android:smoothScrollbar="true" />
android:id="@+id/search_delete_btn"
android:layout_width="match_parent"
android:layout_height="@dimen/height_button"
android:layout_alignParentBottom="true"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginBottom="10dip"
style="@style/textStyle.Normal.black"
android:text="@string/delete_history"
android:background="@drawable/tag_button_bg_unchecked"
android:layout_centerHorizontal="true"/>
onCreate中设置⾃定义标题
@Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
}
搜索记录缓存到SharedPrefreences中
public void loadKey(){
mSearchkeys = new ArrayList();
String searchKey = SPSaveData.getString(this, SPMobileConstants.KEY_SEARCH_KEY); if
(!SPStringUtils.isEmpty(searchKey)){
String[] keys = searchKey.split(",");
if (keys !=null)
for(int i=0; i< keys.length; i++){
if (!SPStringUtils.isEmpty(keys[i])){
mSearchkeys.add(keys[i]);
}
}
}
}
public void saveKey(String key){
String searchKey = SPSaveData.getString(this, SPMobileConstants.KEY_SEARCH_KEY); if
(!SPStringUtils.isEmpty(searchKey) && !searchKey.contains(key)) {
searchKey+=","+key;
}else{
searchKey = key;
}
SPSaveData.putValue(this, SPMobileConstants.KEY_SEARCH_KEY, searchKey);
}
