TextView is a one of the Views available in Android. There are two (2) ways to add TextView in your Android application as follows :
- Using XML code
- Using Java code
XML Code example – Adding to a TextView in a layout xml file
<?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="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hello World" /> </LinearLayout>
Java Code example – Creating and adding a new TextView to a Layout
// Creates object of TextView TextView textView = new TextView(this); // Set text to display in TextView on Screen textView.setText(“Hello World”); // Add TextView to Linear Layout with layout parameters ((LinearLayout)findViewById(R.id.mainLayout)) .addView(textView, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
Above Java code can be written in onCreate() of your Activity.
Here LayoutParams.FILL_PARENT will set layout height to FILL_PARENT, LayoutParams.WRAP_CONTENT will set layout width to WRAP_CONTENT.
