I am pretty new in Android.
I have some problems to create a dynamic LinearLayout programmatically.
I actually have some information in ArrayLists that I need to display. The problem is that I don't know how many items are in the ArrayList, so I need to create the same layout (LinearLayoutChild) for every item in the ArrayList.
For example, I have created this (in this case, let's say the ArrayLists have 2 items each)
ArrayList<String> alistA = new ArrayList<String>();
ArrayList<String> alistB = new ArrayList<String>();
ArrayList<String> alistC = new ArrayList<String>();
ArrayList<String> alistD = new ArrayList<String>();
ArrayList<String> alistE = new ArrayList<String>();
alistA.add(0, "TextA1");
alistA.add(1, "TextA2");
alistB.add(0, "TextB1");
alistB.add(1, "TextB2");
alistC.add(0, "TextC1");
alistC.add(1, "TextC2");
alistD.add(0, "TextD1");
alistD.add(1, "TextD2");
alistE.add(0, "TextE1");
alistE.add(1, "TextE2");
int NumberArray = 2;
for(int i = 0; i<NumberArray;i++){
// How can i do this?
}
I want to display it like :
alistA[0] -> Tv1
alistB[0] -> Tv2
and so on...
alistA[[1]] -> Tv1 (newly created)
alistB[[1]] -> Tv2 (newly created)
...

The EditText and button need to stay at the same place.
Thank you.
Sounds like a good use case for Android's ListView. From Google's documentation:
ListView is a view group that displays a list of scrollable items. The list items are automatically inserted to the list using an Adapter that pulls content from a source such as an array or database query and converts each item result into a view that's placed into the list.
To go this route, update main.xml to include a ListView element -- and move the LinearLayoutChild into its own XML file.
main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
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"
tools:context="com.example.murat.testlol.MainActivity"
android:id="#+id/LinearLayout1"
android:orientation="vertical">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/Et1"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/Btn1"/>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/list"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
generic_linear_layout_child.xml:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="4"
android:orientation="vertical"
android:id="#+id/linear_layout_child">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/Tv1"
android:gravity="center"
android:text="TextView1"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="TextView2"
android:id="#+id/Tv2"
android:gravity="center"/>
</LinearLayout>
Then, create an adapter to bind the data in your array to the appropriate UI elements. Here's a SO post on how to create a custom adapter: Custom Adapter for List View
You need to create the linearlayouts and textviews dynamically, using routines like this:
public TextView makeTextView (String text)
{
TextView tv = new TextView (context)
tv.setText (text) ;
// customise the layout of the text here, eg...
tv.setTextColor(Color.RED) ;
return tv;
}
public LinearLayout makeHorizLayout ()
{
LinearLayout ll = new LinearLayout (context);
ll.setOrientation(LinearLayout.HORIZONTAL);
ll.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
return ll;
}
After you have loaded the schema, you find the view that you want to insert the linearLayouts into like this:
View mainView = findViewById (R.id.LinearLayout1);
You then add a linearlayout to a view like this:
LinearLayout ll = makeHorizlayout ();
mainView.add(ll);
Then you add textviews to the LinearLayout like this:
TextView tv = makeTextView ("whatever text");
ll.addView (tv);
Do the following. Get your data and fill a linearLayout container during runtime after you have retrieved / created your data. Here is an example for creating the views.
private LinearLayout container;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
container = new LinearLayout(this);
container.setOrientation(LinearLayout.VERTICAL)
// + other layout stuff / better inflate this from xml
// Get data and call createLayout with the data
}
createLayout(List<List<String>> lists) {
for (List<String> list : lists) {
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
// + other layout stuff / better inflate this from xml
for (String string : list) {
TextView textView = new AppCompatTextView(this);
textView.setText(string);
linearLayout.addView(textView);
}
container.addView(linearLayout);
}
}

This is my Layout , I have nested Linear layout inside another linear layout which is nested inside an Scroll view. Now i want to add an Linear layout dynamically (I may even add upto 10) inside android:id="#+id/formLayout" i.e beneth android:id="#+id/secondLayout"

Can some one help me with this ?
Use the LayoutInflater to create a view based on your layout template, and then inject it into the view where you need it.
public static NavigableMap<Integer, String> navigableMap = new TreeMap<Integer, String>();
public static int count = 0; // to count no of views added
public static void add_new(final Activity activity)
{
final LinearLayout linearLayoutForm = (LinearLayout) activity.findViewById(R.id.formLayout);
final LinearLayout newView = (LinearLayout) activity.getLayoutInflater().inflate(R.layout.view_to_add, null);
newView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
final EditText edit_new = (EditText) newView.findViewById(R.id.fieldAttr2);
edit_new.setId(id++); // It will assign a different id to edittext each time while adding new view.
Log.i("actv id",edit_new.getId()+""); // You can check the id assigned to it here.
// use a Hashmap or navigable map (helpful if want to navigate through map)
// to store the values inserted in edittext along with its ids.
edit_new.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View view, boolean b) {
navigableMap.put(edit_new.getId(), edit_new.getText().toString());
Log.i("navigablemap", navigableMap.toString());
}
});
// you can get values directly through map by referencing its ids.
// OR
EditText actv_uc = (EditText) linearLayoutForm.findViewById(navigableMap.lastKey());
// Provide the id of edittext you want to access
actv_uc.getText(); // to get value of EditText
actv_uc.setText("");
linearLayoutForm.addView(newView);
count++;
}
Call this function whenever you want to add new view. If you are calling this in Activity, then there is no need to pass Activity object as parameter. but if you are using this in fragment, then need to pass a Parent Activity object to function.
Very easy and helpful tutorial for adding views dynamically :-

Hope this will help you. Thank you
Try this:
LinearLayout myRoot = (LinearLayout) findViewById(R.id.formLayout);
LayoutInflater inf = LayoutInflater.from(yourContext);
View child;
for (int i = 0; i < 10; i++) {
child = inf.inflate(R.layout.your_added_layout, null);
child.setId("textView"+i);
// can set layoutparam if needed.
myRoot.addView(child);
}
I am trying to add multiple LinearLayouts into one declared in xml. Everyone has 3 textView which will be edited in code. My problem is, when i am inflating xml layout to View object in code, all margins are ignored. My second question:
How can i dynamically set ids to textViews and then edit text in it?
LinearLayout xml which is inflating:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/pointsAwaiting"
android:layout_marginTop="40dp"
android:background="#drawable/background_blue"
android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical"
android:padding="10dp">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:textColor="#FFFFFF"
android:textSize="20dp" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="2"
android:textColor="#FFFFFF"
android:textSize="15dp" />
</LinearLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="2"
android:padding="10dp"
android:textColor="#FFFFFF"
android:textSize="20dp" />
</LinearLayout>
He is inflating into this piece of code:
<
ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background"
tools:context="pl.com.qiteq.zielonomocni_rework.HistoryActivity">
<LinearLayout
android:id="#+id/mainView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp">
<LinearLayout
android:id="#+id/historyView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</LinearLayout>
</ScrollView>
And finnaly java code: (loop counter is for example)
LinearLayout mainView = (LinearLayout) findViewById(R.id.historyView);
for (int i=0; i<=2; i++){
View layout = View.inflate(this, R.layout.history_bar, null);
mainView.addView(layout);
}
The reason all your margins are being ignored is that you are passing null into your inflater here:
View layout = View.inflate(this, R.layout.history_bar, null);
When you do this all the LayoutParams of your view are thrown away. You should replace it with:
View layout = inflater.inflate(this, R.layout.history_bar, mainView, false);
To set text in the TextViews you don't need to set a different id for each one, just give each one an id. Then in your loop you can do something like:
List<TextView> textViews = new ArrayList<>();
LayoutInflater inflater = LayoutInflater.from(this);
for (int i=0; i<=2; i++){
View layout = inflater.inflate(this, R.layout.history_bar, mainView, false);
mainView.addView(layout);
TextView textView = (TextView) layout.findViewById(R.id.text1);
textViews.add(textView);
}
You would then have a reference to each of your TextViews in the List
I am trying to map a List<List<Object>> to a RecyclerView in Android, but the result is totally messed up.
For example, I have a list of list like this (just for explaining, not my real case):
List<List<String>> list = {{a, b, c}, {d, e}, {f, g, h, i}};
the Recyclerview should display like (first row contains three subrows, second has two and the last on has four):
|----a-----|
|----b-----|
|----c-----|
|=======|
|----d-----|
|----e-----|
|=======|
|----f-----|
|----g-----|
|----h-----|
|----i-----|
but the result is not exactly like the above order. some element is duplicated and some disappears. for example:
|----d-----|
|----e-----|
|----c-----|
|=======|
|----d-----|
|----e-----|
|=======|
|----f-----|
|----a-----|
Here is a piece of my code:
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
List<Event> list = eventList.get(position);
if (holder.rows < list.size()) {
holder.rowViewGroup.removeAllViews();
holder.rows = 0;
ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
TextView startView = new TextView(context);
startView.setLayoutParams(layoutParams);
Event headEvent = list.get(0);
Calendar startCal = headEvent.getStartCal();
startView.setText(String.format("%tD", startCal));
holder.rowViewGroup.addView(startView);
for (final Event event : list) {
View element = LayoutInflater.from(context).inflate(R.layout.element, null);
//start time view
TextView startTimeView = (TextView)element.findViewById(R.id.eventStartTimeInElement);
Calendar startTimeCal = event.getStartCal();
startTimeView.setText(String.format("%tl:%tM %tp", startTimeCal, startTimeCal, startTimeCal));
//end date time view
TextView endView = (TextView)element.findViewById(R.id.eventEndTimeInElement);
Calendar endCal = event.getEndCal();
endView.setText(String.format("%tD %tl:%tM %tp", endCal, endCal, endCal, endCal));
//title view
TextView title = (TextView)element.findViewById(R.id.eventTitleInElement);
title.setText(event.getTitle());
//member name
Drawable divider = context.getResources().getDrawable(R.drawable.divider);
ImageView dividerView = new ImageView(context);
dividerView.setImageDrawable(divider);
holder.rowViewGroup.addView(dividerView);
holder.rowViewGroup.addView(element);
holder.rows++;
}
}
}

And I know this is not a really good idea to implement this, so could anybody please tell me a better way to implement this? Thanks...
I think your best bet is to flatten your list of lists into one list.
This is just for purposes of the ListView. Your adapter will act as though the lists have all been strung into one long list.
Start by creating a single-list index for all the items of your nested lists.
For example:
List<List<String>> listOfLists = ... // your original data
List<String> listForView = new ArrayList<String>();
for (List<String> innerList : listOfLists) {
for (String str : innerList) {
listForView.add(str);
}
listForView.add("---"); // e.g. marker value for divider
}
Now in your adapter's getItem() need only return listForView.get(position).
Anytime your nested list structure changes, you redo this flattening operation and call notifyDataSetChanged().
Things get a little trickier if — given the position — you have to figure out which list an item is in, but you could always index the inner lists in a similar fashion.
private void showText(){
textView.setText(Html.fromHtml(text));
Log.d("MyLog","tags.size="+tags.size());
for (int i=0;i<tags.size();i++){
Button button = new Button(context);
button.setText(tags.get(i));
ll.addView(button, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));
tagButtons.add(button);
}
}
This should be simple but this buttons doesn't show. I checked with logs- tags.size=5 so the problem is not in this. ll is a LinearLayout
Here's layout file :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ScrollView
android:layout_margin="5dp"
android:id="#+id/scrollView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<LinearLayout
android:orientation="horizontal"
android:id="#+id/ll2"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="TextView" />
<LinearLayout
android:id="#+id/ll"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>
So, it's a very simple code and I don't understand why are theese views are not being added to a layout with id "ll"
You should call invalidate() on the parent layout which forces children to be drawn on the screen
Remove the linearlayout reference which you have not posted in the question and use like as i have done, Try this
Call showText() in OnCreate- method If you are using Activities
private void showText(){
textView.setText(Html.fromHtml(text));
for (int i=0;i<tags.size();i++){
Button button = new Button(context);
button.setText(tags.get(i));
LinearLayout ll=(LinearLayout) findViewById(R.id.ll);
ll.addView(button);
}
}
I Have activity that get some data from the internet, and shows it to the screen.
I'm using scroll view cause it's long text, I also want different text style for a different data,so I use few textViews with a different style and to show it on the Activity screen,
my problem is that scroll view can handle only one view, so how can I use scrolling to show different style of Text view, I tried to add LinearLayout to the scrollView and add all the textViews dynamically in code to this LinearLayout ,but I'm getting exception - scroll view can host only one direct child.
The code below:
/** this is the function, which called from the onClick method.
wanted data object contains 2 strings title message and the message itself.
When debug the code i can see that there's two String values in each loop.
but i cant add the linearLayout to my scrollView - exception ScrollView can host only one direct child */
private void showResult(ArrayList<WantedData> result) {
// TODO Auto-generated method stub
TextView title;
TextView data;
scrollLayout = (LinearLayout) findViewById(R.id.LlScrollView);
for (WantedData curr : result) {
if (curr.getTitle() == null) {
break;
}
title = new TextView(this);
title.setText(curr.getTitle());
scrollLayout.addView(title, LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
data = new TextView(this);
data.setText(curr.getData());
scrollLayout.addView(data, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
}
scroll.addView(scrollLayout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
//at the onCreate method - scroll = (ScrollView) findViewById(R.id.SvShowTextFromServer);
}

The problem is double creating of container in ScrollView. You should not create it in activity, but take already defined from xml:
LinearLayout scrollContainer = (LinearLayout)findViewById(R.id.LlScrollView);
for (...) {
//create here some text
scrollLayout.addView(text);
}
If you have defined a LinearLayout in XML you don't have to create a new LinearLayout in your code but you have to retrieve the existing one in this way
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.LlScrollView);
Otherwise you have to remove the LinearLayout in your XML and add all by code.
