Ich versuche, eine ListView anzuzeigen. Ich möchte auch, dass meine App-Benutzer in der Lage sein werden, den ListView nach unten zu scrollen, wenn es benötigt wird. Also machte ich dies:Android ListView in einem ScrollView
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#cacaca">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.giladneiger.clubber.Party_List_Activity"
tools:showIn="@layout/activity_party__list_"
android:background="#cacaca">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/listView1"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:contextClickable="true"
android:textColor="#FFFFFF"
style="@style/ListViewStyle"
android:background="#4c008b"
android:layout_marginTop="60dp"
android:divider="#cacaca"
android:dividerHeight="15dp" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Now Events:"
android:id="@+id/textView11"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:textSize="30dp"
android:textColor="#7e008d"
android:textStyle="bold" />
</RelativeLayout>
</ScrollView>Das Problem, das ich bin exeperiencing, ist, dass Android-Listenansicht aus der Scrollview ist ausschließlich als die Scrollview bereits eine Scroll-able Funktion hat. Ich möchte, dass der listView so lange ist, wie der Inhalt ist und dass die Master-Bildlaufansicht scrollbar ist.
Ich habe versucht, diese Anleitung zu verwenden: Android list view inside a scroll view
Aber es funktioniert nicht. Es ist immer noch das gleiche Problem.
Dies ist mein Code:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_party__list_);
Firebase.setAndroidContext(this);
firebaseRef = new Firebase(FIREBASE_URL);
final ListView listView = (ListView) findViewById(R.id.listView1);
populatePartyList();
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
openPartyInfo(parent, view, position, id);
}
});
}
public static void setListViewHeightBasedOnChildren(ListView listView, ListAdapter adapter) {
//ListAdapter listAdapter = listView.getAdapter();
int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.UNSPECIFIED);
int totalHeight = 0;
View view = null;
for (int i = 0; i < adapter.getCount(); i++) {
view = adapter.getView(i, view, listView);
if (i == 0)
view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth, RelativeLayout.LayoutParams.WRAP_CONTENT));
view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
totalHeight += view.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (adapter.getCount() - 1));
listView.setLayoutParams(params);
}
private void populatePartyList() {
firebaseRef.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot snapshot) {
ArrayList<String> subTitles = new ArrayList<String>();
ArrayList<PartyClass> partyList = new ArrayList<PartyClass>();
ArrayList<String> titles = new ArrayList<String>();
for (DataSnapshot user : snapshot.child("users").getChildren()) {
if (user.child("party/party_title").exists()) {
if (dateRelevant(user.child("party/party_date").getValue().toString()) == true) {
String party_title = user.child("party/party_title").getValue().toString();
String party_date = user.child("party/party_date").getValue().toString();
//dateRelevant(party_date);
subTitles.add(party_date);
String party_content = user.child("party/party_content").getValue().toString();
String age_limit = user.child("party/age_limit").getValue().toString();
String party_hour = user.child("party/party_hour").getValue().toString();
String location_left = user.child("location_left").getValue().toString();
String location_right = user.child("location_right").getValue().toString();
PartyClass oneParty = new PartyClass(party_title, party_date, party_content, age_limit, party_hour, location_left, location_right);
partyList.add(oneParty);
}
}
}
for (PartyClass party : partyList) {
titles.add(party.getParty_title());
}
ArrayAdapter adapter = new ArrayAdapter(Party_List_Activity.this, android.R.layout.simple_list_item_1, titles) {
@Override
public View getView(int position, View convertView,
ViewGroup parent) {
View view = super.getView(position, convertView, parent);
TextView textView = (TextView) view.findViewById(android.R.id.text1);
textView.setTextColor(Color.WHITE);
return view;
}
};
ListView listView = (ListView) findViewById(R.id.listView1);
listView.setAdapter(adapter);
setListViewHeightBasedOnChildren(listView, adapter);
}
@Override
public void onCancelled(FirebaseError firebaseError) {
String message = "Error";
Toast.makeText(Party_List_Activity.this, message, Toast.LENGTH_SHORT).show();
}
});
}
