Android: Adding view dynamically in a nested layout

android, android-linearlayout, dynamic, view

Solution

your xml should be

<ScrollView
  android:layout_width="match_parent"
  android:layout_height="match_parent">
 <LinearLayout
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:orientation="vertical">
  <LinearLayout
    android:id="@+id/linear"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
  </LinearLayout>
 </LinearLayout>
</ScrollView>

and the java code to add your text view is

LinearLayout layout = (LinearLayout) view.findViewById(R.id.linear);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
    LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
TextView Tag = new TextView(getActivity());
tag.setLayoutParams(params);
Tag.setText("textString");
Tag.setBackgroundResource(R.color.bg_color);
Tag.setTextAppearance(getActivity(), R.style.SmallFont);
layout.addView(Tag);

Problem

I have an abc.xml with the following structure. ``` <ScrollView android:layout_width="match_parent" android:layout_height="match_parent"> <RelativeView android:layout_width="match_parent" android:layout_height="wrap_content"> <LinearLayout android:id="@+id/linear" android:layout_width="wrap_content" android:layout_height="wrap_content" > </LinearLayout> </RelativeLayout> </ScrollView> ``` I want to add textviews dynamically to linear layout. Below is my code. I don't get any errors but I am not getting the desired results. ``` LayoutInflater Inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE); View view = Inflater.inflate(R.layout.abc, null); LinearLayout layout = (LinearLayout) view.findViewById(R.id.linear); TextView Tag = new TextView(getActivity()); Tag.setText("textString"); Tag.setBackgroundResource(R.color.bg_color); Tag.setTextAppearance(getActivity(), R.style.SmallFont); layout.addView(Tag); ```
