我遇到了一个让我疯狂的SearchView的问题。 我已按照此问题的答案中建议的方法在ActionBar中实现了SearchView:
Implementing SearchView in action bar
我已根据自己的需要修改了建议的代码,因此建议根据输入的内容进行过滤,并且效果很好,除了我无法使OnSuggestionListener工作!
包含SearchView操作栏的活动的相关部分:
public class MyGroupsActivity extends ActionBarActivity {
private List<String> allItems;
private Menu menu;
private SearchView searchView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_groups);
allItems = getAllItems();
}
@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_my_groups, menu);
this.menu = menu;
// Associate searchable configuration with the SearchView
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(manager.getSearchableInfo(getComponentName()));
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String s) {
System.out.println("onQueryTextSubmit " + s);
return true;
}
@Override
public boolean onQueryTextChange(String query) {
loadHistory(query);
return true;
}
});
}
return true;
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void loadHistory(String query) {
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
String[] columns = new String[] { "_id", "text" };
Object[] temp = new Object[] { 0, "default" };
MatrixCursor cursor = new MatrixCursor(columns);
List<String> result = new ArrayList<>();
for(int i = 0; i < allGroups.size(); i++) {
if(allItems.get(i).toLowerCase().contains(query.toLowerCase())){
temp[0] = i;
temp[1] = allItems.get(i);
cursor.addRow(temp);
result.add(allItems.get(i));
}
}
searchView.setSuggestionsAdapter(new SearchViewAdapter(this, cursor, result));
searchView.setOnSuggestionListener(new SearchView.OnSuggestionListener() {
@Override
public boolean onSuggestionSelect(int i) {
System.out.println("onSuggestionSelect");
Cursor cursor = (Cursor) searchView.getSuggestionsAdapter().getItem(i);
String feedName = cursor.getString(1);
searchView.setQuery(feedName, false);
searchView.clearFocus();
return true;
}
@Override
public boolean onSuggestionClick(int i) {
System.out.println("onSuggestionClick");
Cursor cursor = (Cursor) searchView.getSuggestionsAdapter().getItem(i);
String feedName = cursor.getString(1);
System.out.println(feedName + " clicked ");
searchView.setQuery(feedName, false);
searchView.clearFocus();
return true;
}
});
}
}
}
我的CustomAdapter子类:
public class SearchViewAdapter extends CursorAdapter {
private List<String> items;
private TextView text;
public SearchViewAdapter(Context context, Cursor cursor, List<String> items) {
super(context, cursor, false);
this.items = items;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
text.setText(items.get(cursor.getPosition()));
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.search_item, parent, false);
text = (TextView) view.findViewById(R.id.textView);
return view;
}
}
我的search_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
android:id="@+id/textView"
android:layout_margin="5dp"
android:textColor="@color/accent" />
</RelativeLayout>
我尝试使用OnClickListener,我已经尝试将它放在CustomAdapter的bindView方法中,我已经尝试在onCreate中实例化适配器,以及许多其他的东西,我甚至都不记得它们现在..似乎没什么工作。当我点击建议列表中的项目时,我进入logcat的所有内容都是:
D/ViewRootImpl﹕ ViewPostImeInputStage ACTION_DOWN
所以,说清楚 - 如何检测建议点击并获取项目的价值?
非常感谢任何帮助和评论!谢谢!

我有一个正常工作的代码,我在设置建议适配器之前设置了onSuggestionListener。你可以尝试一下吗?

使它起作用的唯一方法是直接在CursorAdapter的视图上绑定自己的onClickListener,而根本不使用onSuggestionListener。
