**How to Add a TextView to a LinearLayout in Android?**

Adding a TextView to a LinearLayout in Android

Question:

In an XML-defined layout, a LinearLayout is declared to dynamically add TextViews. However, an attempt to do so results in a ClassCastException: android.widget.TextView error.

Answer:

To rectify the error, the following steps should be taken:

  1. Cast the LinearLayout to the correct type:

    <code class="java">LinearLayout linearLayout = (LinearLayout) findViewById(R.id.info);</code>
  2. Ensure that the LayoutParams used for the TextView are LinearLayout.LayoutParams:

    <code class="java">valueTV.setLayoutParams(new LinearLayout.LayoutParams(
        LayoutParams.FILL_PARENT,
        LayoutParams.WRAP_CONTENT));</code>
  3. Add the TextView to the LinearLayout:

    <code class="java">linearLayout.addView(valueTV);</code>
