Dynamically adding TextViews to this layout results in text not being wrapped.
<!-- R.layout.description_card -->
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout_InfoShow"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="#dimen/table_row_padding_bottom" >
<TableLayout
android:background="#drawable/card_bg"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TableRow
android:id="#+id/TableRow_DescriptionTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/DescriptionTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-light"
android:textSize="#dimen/page_name_size"
android:text="Loading data..." />
</TableRow>
<TableRow
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/DescriptionTitle">
<LinearLayout android:id="#+id/LinearLayout_Description"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- Dynamically added TextView here -->
</LinearLayout>
</TableRow>
</TableLayout>
</LinearLayout>
I dynamically add the TextViews to this layout using these methods:
View view = inflater.inflate(R.layout.description_card, null);
TextView title = (TextView) view.findViewById(R.id.DescriptionTitle);
LinearLayout description = (LinearLayout) view.findViewById(R.id.LinearLayout_Description);
ArrayList<TextView> textViews = des.getText();
Iterator<TextView> iter = textViews.iterator();
while(iter.hasNext()){
TextView textView = iter.next();
description.addView(textView);
}
This results in my textviews not wrapping onto new lines, even though it works perfectly fine if I include the TextView directly in the XML file.
It results in this:
Edit:
TextView layout:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/TextViewDescription"
style="#style/AppTheme"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:paddingRight="8dp"
android:text="Loading data..."
android:textSize="#dimen/description_size"
android:layout_weight="1"
android:ellipsize="none"
android:scrollHorizontally="false" />
You probably need to set it to multi line. Try
setInputType (InputType.TYPE_TEXT_FLAG_MULTI_LINE);
If you have other InputType attributes, you'll need to "or" them together.
At this part of your code, you are getting your TextView array:
ArrayList<TextView> textViews = des.getText();
And we don't see how those TextView's are created. But I assume you did not set single_line or max_lines to TextViews.
Try this code while adding your TextViews to your LinearLayout:
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
while (iter.hasNext()) {
TextView textView = iter.next();
description.addView(textView, params);
}
Edit:
Use below layout while creating your TextViews(I've removed some attrs and style.):
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/TextViewDescription"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:paddingRight="8dp"
android:text="Loading data..."
android:textSize="#dimen/description_size"/>
Edit2: Change your layout_width param to wrap_content. Also see updated param at code above. (This worked for me)
<LinearLayout android:id="#+id/LinearLayout_Description"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<!-- Dynamically added TextView here -->
</LinearLayout>
Try using something other than TableLayout. I'm not very experienced with TableLayout but I think it needs the child views to have relatively short and consistent widths.
Instead, try using LinearLayout, like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout_InfoShow"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="#dimen/table_row_padding_bottom" >
<TextView
android:id="#+id/DescriptionTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-light"
android:textSize="#dimen/page_name_size"
android:text="Loading data..." />
<!-- Dynamically added TextView here -->
</LinearLayout>
And add the views with more-or-less the same code you had before. Note I changed the parent view for supporting the adds -- outerLayout.
View view = inflater.inflate(R.layout.description_card, null);
TextView outerView = (TextView) view.findViewById(R.id.LinearLayout_InfoShow);
ArrayList<TextView> textViews = des.getText();
Iterator<TextView> iter = textViews.iterator();
while(iter.hasNext()) {
TextView textView = iter.next();
outerView.addView(textView);
}
Found the reason.
The inflater needed a ViewGroup for the layout params to take effect.
I had to change the way I pass the text through to the iterator but this is basically what needed changing:
TextView textView = (TextView) inflater.inflate(text.getViewID(), description, false);
For the problem...
When you have
<TableLayout>
<TableRow>
<TextView>
</TextView>
</TableRow>
</TableLayout>
to make the text appear without truncation,
add
android:layout_weight="1"
inside the textview
<TextView>
</TextView>

A page on my app has a table layout page, and one row of it seems to not be working. My goal is to evenly split the page between the left cell and right cell. The left cell contains a string, the right cell an image and string. I have tried to do so using weighSum. The left cell got weight of 4/8, and right cell was put into a linear layout, within which the image got weight of 1/8 and the string got weight 3/8. However, in the layout the left cell is taking up the great majority of the row, about 75% and I'm not sure why.
My rows below this one attempt almost the same thing, but don't have the same problem.
My xml(cut for relevancy):

The first table row is the problematic one - it should be evenly split between the left and right cells, but is mostly towards the right.
The second table row is an example of it working correctly - this row has 2 pairs of cells, but each of the cells, and the pairs of cells are correctly splitting the width between themselves evenly.
I can't figure out why the first doesn't work. I appreciate any help!
I have finally succeeded in fixing the layout!
The method used was to <include /> another layout as a row element inside this one. All these row elements had the same data, so I then programmatically filled the row elements with their necessary data whenever the view changed. You could also do this as a ListView, with each row in the ListView being another pair of elements, but I'm not sure how well that works for the 4 element wide rows.
The XML of each row:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2">
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/statNameString"
android:id="#+id/statName"
android:layout_marginTop="30dp"
android:gravity="center" />
<View
android:layout_width="4dp"
android:gravity="left"
android:layout_height="match_parent"
android:background="#663300"/>
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="#string/statValString"
android:id="#+id/statVal"
android:layout_marginTop="30dp"
android:gravity="center" />
</LinearLayout>
The top row(which represented the Class of the Character in my app) needed to include an ImageView, so it had a slightly changed layout. The ImageView was placed after the bar View, and before the last TextView.
The XML including each row into the final layout, for the Land layout:
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
layout="#layout/horizontal_class_row_layout"
android:id="#+id/strValues"
android:layout_column="0" />
<include
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
layout="#layout/horizontal_class_row_layout"
android:id="#+id/intValues"
android:layout_column="0" />
</TableRow>
If you only wanted 1 pair of elements in each row, you can simply remove one of the include tags. As mentioned before, you could also use the ListView to do these, and fill the data, and I will probably modify it to do that eventually.
Finally, you programmatically fill the elements with their data in the Java, so they don't just say "Class" and "Class Value" or whatever default data:
private void fillViewValues() {
//Gather views
LinearLayout llClass = (LinearLayout)findViewById(R.id.classValues);
LinearLayout llStr = (LinearLayout)findViewById(R.id.strValues);
LinearLayout llDex = (LinearLayout)findViewById(R.id.dexValues);
LinearLayout llCon = (LinearLayout)findViewById(R.id.conValues);
LinearLayout llInt = (LinearLayout)findViewById(R.id.intValues);
LinearLayout llWis = (LinearLayout)findViewById(R.id.wisValues);
LinearLayout llCha = (LinearLayout)findViewById(R.id.chaValues);
//Get the layout's locations
TextView classNameView = (TextView) llClass.findViewById(R.id.statName);
TextView classValView = (TextView) llClass.findViewById(R.id.statVal);
ImageView classImage = (ImageView) llClass.findViewById(R.id.classicon);
TextView strNameView = (TextView) llStr.findViewById(R.id.statName);
TextView strValView = (TextView) llStr.findViewById(R.id.statVal);
TextView dexNameView = (TextView) llDex.findViewById(R.id.statName);
TextView dexValView = (TextView) llDex.findViewById(R.id.statVal);
TextView conNameView = (TextView) llCon.findViewById(R.id.statName);
TextView conValView = (TextView) llCon.findViewById(R.id.statVal);
TextView intNameView = (TextView) llInt.findViewById(R.id.statName);
TextView intValView = (TextView) llInt.findViewById(R.id.statVal);
TextView wisNameView = (TextView) llWis.findViewById(R.id.statName);
TextView wisValView = (TextView) llWis.findViewById(R.id.statVal);
TextView chaNameView = (TextView) llCha.findViewById(R.id.statName);
TextView chaValView = (TextView) llCha.findViewById(R.id.statVal);
//Fill those values
//Names of sections
classNameView.setText(getResources().getString(R.string.classString));
strNameView.setText(getResources().getString(R.string.strString));
dexNameView.setText(getResources().getString(R.string.dexString));
conNameView.setText(getResources().getString(R.string.conString));
intNameView.setText(getResources().getString(R.string.intString));
wisNameView.setText(getResources().getString(R.string.wisString));
chaNameView.setText(getResources().getString(R.string.chaString));
//Values
classValView.setText(classString);
setImage(classImage, classString);
strValView.setText(String.format("%d", finalStats[0]));
dexValView.setText(String.format("%d", finalStats[1]));
conValView.setText(String.format("%d", finalStats[2]));
intValView.setText(String.format("%d", finalStats[3]));
wisValView.setText(String.format("%d", finalStats[4]));
chaValView.setText(String.format("%d", finalStats[5]));
}
This follows the advice at at this StackOverflow post.
One thing I would like to note, is that when you change the layout, you need to reset the content view to your current layout. In my case, the function looked like:
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
{
setContentView(R.layout.activity_see_character);
fillViewValues();
}else if(newConfig.orientation == Configuration.ORIENTATION_PORTRAIT)
{
setContentView(R.layout.activity_see_character);
fillViewValues();
}
}
where fillViewValues() is the previous function. I believe that this sets the layout to either the portrait or landscape version of the layout, which can then have its elements accessed. If you don't do this when you try to access the elements it can't find them and gives a NullPointerException.
I have a ScrollView that I am trying to populate dynamically. Here is the XML that contains the ScrollView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#f6f5f5" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#40ff0000"
android:paddingBottom="70dp"
android:paddingTop="20dp"
android:paddingLeft="20dp"
android:paddingRight="20dp">
<LinearLayout
android:id="#+id/option_list_container"
android:background="#40ffff00"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:background="#292929"
android:paddingBottom="5dp"
android:paddingLeft="15dp"
android:paddingTop="5dp"
android:text="Stap 3/5"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/white" />
</LinearLayout>
</ScrollView>
And here is the XML for the element I'm inserting in the ScrollvVew:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<np.custom.FontIcon
android:id="#+id/option_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/calendar_circleround"
android:textSize="40sp"
android:gravity="center"
android:text="#string/planit_selection_empty_circle"
android:textColor="#292929" />
<TextView
android:id="#+id/option_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:layout_marginLeft="10dp"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
This is the code I use to populate the scrollview:
ArrayList<String> g = new ArrayList<String>();
g.add("Fix a Bug");
g.add("Buy a new PC");
g.add("Make Coffee");
g.add("Take a Break");
g.add("Don't do that");
g.add("Throw your hands in the air like you just don't care!");
LinearLayout optionListLayout = (LinearLayout) rootView.findViewById(R.id.option_list_container);
LayoutInflater inflater = LayoutInflater.from(getActivity());
for(String p:g){
View v = inflater.inflate(R.layout.planit_option_item, null);
TextView optText = (TextView) v.findViewById(R.id.option_text);
optText.setText(p);
optionListLayout.addView(v);
}
This all works almost fine, except that the sizes of the ScrollView and the LinearLayout it contains do not come out as I expected. This a screenshot of that it looks like on a device, which shows text being cut out when it goes to a second line:
So how can I make sure the linear layout re-sizes to accommodate children views of different heights?
Your issue isn't the ScrollView not accommodating new children. The problem is that the text, when it spans more than one line, is being clipped due to layout parameters in R.layout.planit_option_item. Try changing the TextView of ID #+id/option_text so that its height is wrap_content.
Change your TextView for the ScrollView element to accommodate two lines:
...
<TextView
android:id="#+id/option_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:layout_marginLeft="10dp"
android:maxLines="2"
android:singleLine="false"
android:textAppearance="?android:attr/textAppearanceMedium" />
...
This is not an issue with ScrollView, it's an issue with the specifications of the element you are inserting into the ScrollView. If you expect there may be more than 2 lines of text in some cases set maxLines = X where X is the maximum number of lines you expect.
Please let me know if this does not work and I would be happy to help further.
I have a layout where I put i rows dynamically in a tablelayout that is inside a scrollview. Everything is working smoothly except that I don't can get the checkbox text to wordwrap (See xml below). The text is also set at runtime. I have searched the internet and has made a lot of trying to set different properties with no luck so far.
Is this task possible to achieve?
<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="15dip">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<CheckBox
android:id="#+id/bes_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="" />
<EditText
android:id="#+id/bes_kommentar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/bes_checkbox" />
</RelativeLayout>
</TableRow>
CheckBox extends TextView, so I assume you can wrap its text like they solve the issue in this post :
Android TextView Text not getting wrapped
If you cannot get it to work like that, you can maybe also try, using match_parent in the checkbox.
<CheckBox
android:id="#+id/bes_checkbox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="" />
hope it helps.
use table row inside the Linear layout instead of table layout..

I have made dynamic layouts with checkboxes in the past and used this approach:
// Create new view to add layout to
sv = new ScrollView(this);
// Create new layout to add check boxes to
ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
// Add layout to view
sv.addView(ll);
// Create 6 check boxes
int itemSize = 6;
for(int j=0; j<itemSize; j++){
CheckBox cb = new CheckBox(this);
cb.setText("number " + j);
ll.addView(cb);
}
// Finalize view
this.setContentView(sv);
Is this what you are looking for?

Now in my Main activity I am calling the main.xml and based on the for loop condition I want to add the layout of the child.xml and every time I want to set the different value of the TextView of child.xml
So how it is Possible?
I have done like this:
private void doCalculationForMultipleEmployee() {
singleEmployee.setVisibility(View.GONE);
for (int i = 0; i<=tempEmployerList.size()-1; i++) {
View repeatedLayout = LayoutInflater.from(getApplicationContext()).inflate(R.layout.test);
((TextView)repeatedLayout.findViewById(R.id.list_title)).setText("Employee"+i);
// customize repeatedLayout with other data
myLinearLayout.addChild(repeatedLayout);
}
}
But after doing that I got syntax error at .inflate and at .addChild
So where have I gone wrong? Please help me by some code to add it by for loop.
Just create a loop like below:
LinearLayout parent=findViewById(R.id.myLayout);
for(int i=0;i<list.size();i++)
{
LinearLayout llItem=(LinearLayout)LayoutInflater.createFromSource(R.layout.child, null);
TextView txt= (TextView)llItem.findViewById(R.id.title);
txt.setText(list.get(i));
parent.add(llItem);
}
Inflate the view then add to the parent
LinearLayout parent = (LinearLayout)findViewById(R.id.myLayout);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Layout child = inflater.inflate(R.layout.myLayout2, null);
TextView title = (TextView)child.findViewById(R.id.list_title);
parent.addView(child);
Repeat as many times as necessary or use a loop
If i understood your question correctly you need to display button, textview and button side by side in your layout.
If you want this you just take listview and use custom adapter, with this you can display button, text and button side by side

I'm getting a NullPointerException on the line:
tvCsAddLink.setText(txt);
Use this to get TextView from layout.
TextView tvCsAddLink = (TextView)rowLink.findViewById(R.id.tvCsAddLink);
you have inflated your XML on your linearLayout rowLink , and you try to find the TextView from the layout of your Activity ( usualy main.xml ) , so you need to find your textView on your layout rowLink like this :
TextView tvCsAddLink = (TextView)rowLink.findViewById(R.id.tvCsAddLink);
Call findViewById(R.id.tvCsAddLink) on your inflated LinearLayoutrowLink, now you are searching it in the current activity.
