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 TextView
s.
Try this code while adding your TextView
s 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 TextView
s(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>
