如何实现浮动SearchWidget Android
作者：互联网
我正在尝试在当前的Android应用程序中实现搜索小部件,但是无法完成它并且我无法实现它.以下是我的代码
主要活动
@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);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.search_bar).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
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;
} else if (id == R.id.search_bar) {
//startActivity(new Intent(this, SearchResultActivity.class));
return true;
}
return super.onOptionsItemSelected(item);
}
菜单项
<item android:id="@+id/search_bar"
android:title="Search"
android:orderInCategory="100"
android:icon="@android:drawable/ic_menu_search"
app:showAsAction="always|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"/>
SearchActivity
public class SearchResultActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search_custom_text);
handleIntent(getIntent());
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
}
}
}
表现
<activity android:name=".MainActivity"
android:enabled="true">
<!--<meta-data android:name="android.app.searchable"
android:resource="@xml/searchable"/>-->
<meta-data android:name="android.app.default_searchable"
android:value=".SearchResultActivity"/>
</activity>
<activity android:name=".SearchResultActivity"
android:enabled="true"
android:launchMode="singleTop"
android:parentActivityName=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.SEARCH"/>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<!--<meta-data android:name="android.app.default_searchable"
android:value=".SearchResultActivity" />-->
<meta-data android:name="android.app.searchable"
android:resource="@xml/searchable"/>
</activity>
这就是我的想法,但我还没有尝试过.我确实在我的项目中实现了一个浮动活动.从下面的内容来看,我认为这是一个浮动的活动权利.
任何帮助,将不胜感激.
解决方法:
就我而言,我曾经这样使用过
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
menu.add("Search").setIcon(android.R.drawable.ic_menu_search).setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getTitle().toString().equalsIgnoreCase("Search")){
showSearchDialog();
}
return true;
}
private void showSearchDialog() {
// TODO Auto-generated method stub
dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dialog_search);
final Window window = dialog.getWindow();
window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
findDialogViews(dialog);
dialog.show();
}
private void findDialogViews(final Dialog dialog) {
// TODO Auto-generated method stub
ImageView iv = (ImageView)dialog.findViewById(R.id.calc_clear_txt_Prise);
lvSuggestions = (ListView)dialog.findViewById(R.id.listView1);
lvSuggestions.setOnItemClickListener((android.widget.AdapterView.OnItemClickListener) this);
final EditText etSearch = (EditText)dialog.findViewById(R.id.calc_txt_Prise);
iv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(etSearch.getText().toString().isEmpty()){
dialog.dismiss();
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}
else
etSearch.setText("");
}
});
etSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
**DO YOUR STUFF**
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
}
SearchAdapter代码：
public class SearchAdapter extends BaseAdapter{
private Context mContext;
private List<SearchModel> list;
private RequestQueue mRequestQueue;
private ImageLoader mImageLoader;
public SearchAdapter(Context mContext, List<SearchModel> list) {
// TODO Auto-generated constructor stub
this.mContext = mContext;
this.list = list;
mRequestQueue = Volley.newRequestQueue(mContext);
mImageLoader = new ImageLoader(mRequestQueue, new LruBitmapCache());
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return list.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
if(convertView==null){
convertView = LayoutInflater.from(mContext).inflate(R.layout.list_item_search , parent, false);
}
NetworkImageView image = (NetworkImageView)convertView.findViewById(R.id.imageView1);
TextView tvName = (TextView)convertView.findViewById(R.id.textView1);
SearchModel model = list.get(position);
image.setImageUrl(model.getImage(), mImageLoader);
tvName.setText(model.getVName());
return convertView;
}
}
SearchAdapter是设置下拉列表……
