我有一个附加在主要活动上的操作栏。活动托管有许多不同的片段。在操作栏中有菜单项。一种是搜索视图。我声明如下:
菜单xml。
<item android:id="@+id/action_search"
android:title="@string/search"
android:icon="@drawable/ic_search_black"
app:showAsAction="always"
app:actionViewClass= "android.support.v7.widget.SearchView"/>
在主要活动中:
@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);
// Associate searchable configuration with the SearchView
MenuItem item = menu.findItem(R.id.action_search);
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return super.onCreateOptionsMenu(menu);
}
搜索视图起作用,当我单击图标时,搜索视图会展开。我需要捕获搜索视图的点击,因为当用户单击搜索视图时,我要显示一个向用户显示其最近搜索列表的视图。
我还将像这样使用搜索视图:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getSupportMenuInflater().inflate(R.menu.main, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.menu_search)
.getActionView();
if (null != searchView) {
searchView.setSearchableInfo(searchManager
.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
}
SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
public boolean onQueryTextChange(String newText) {
// this is your adapter that will be filtered
return true;
}
public boolean onQueryTextSubmit(String query) {
//Here u can get the value "query" which is entered in the search box.
}
};
searchView.setOnQueryTextListener(queryTextListener);
return super.onCreateOptionsMenu(menu);
}
并在用户键入3个或更多字符时执行搜索。
我在活动中尝试过此操作:
@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.
switch (item.getItemId()){
case R.id.action_search:
L.i("search", "search");
return false;
case android.R.id.home:
L.i("home", "home pressed");
break;
case R.id.action_done:
L.i("done", "done pressed");
break;
default:
;;
}
return super.onOptionsItemSelected(item);
}
它识别完成的菜单项,但不识别搜索。我将需要能够获得点击的活动和片段。
因此,如果有人可以指出我要去哪里的地方。
哦,在我添加的片段中
setHasOptionsMenu(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.
switch (item.getItemId()){
case R.id.action_search:
L.i("search", "search");
return false;
case android.R.id.home:
L.i("home", "home pressed");
break;
case R.id.action_done:
//for testing
checkSelectedInterests();
//TODO: MLC
L.i("done", "done pressed");
break;
default:
;;
}
return super.onOptionsItemSelected(item);
}
所以如果有人可以帮助我,我将不胜感激
所以我想通了。据我所知,这不能通过onOptionsItemSelected方法来完成。
因此,我在搜索视图上设置了一个onclicklistener,但该按钮也不起作用。经过仔细检查,我需要如下设置和onSearchClickListener:
searchView.setOnSearchClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
L.i(getClass().getSimpleName(), "SearchViewCLicked");
}
});
希望能帮助某人!
这是一个简单的解决方案,将onActionExpandListener设置为菜单项,如下所示:
@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, menu);
// Get the MenuItem for the action item
MenuItem actionMenuItem = menu.findItem(R.id.action_search);
// Define the listener
actionMenuItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
@Override
public boolean onMenuItemActionExpand(MenuItem item) {
// Do what you want when it expands
return true;
}
@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
// Do what you want when it collapses
return true;
}
});
return true;
}
