TextView

The Android TextView component is a View subclass which is capable of showing text. Being a subclass of View the TextView component can be used in your Android app’s GUI inside a ViewGroup, or as the content view of an activity.

Properties of TextView:

text: defines the text that would be displayed on the screen.

textStyle: sets the style of the text. The possible choices are bold, italic and normal.fontFamily: specifies the font family for the text.

typeFace: as you can imagine it defines the typeface for the text. The possible values are normal, sans, serif and monospace.

textSize: defines the size of the text. It is recommended to use sp for the size.

textColor: sets the color of the text. The color has to be defined in hex encoding or as a reference to another resource.

lines: defines the exact height of the TextView in lines.

The above properties we mentioned in XML file like below code. Here we specified content (text) manually xml file itself.

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/tv" 
    android:textSize="20sp"
    android:textColor="#234098"
    android:textAllCaps="true"
    android:textStyle="bold|italic"
    android:id="@+id/tv"
    android:typeface="monospace"
    android:gravity="center"/>

For the above textview am assigning text dynamically from java with below code

TextView textView;
textView= (TextView) findViewById(R.id.tv);
textView.setText("Hi Hello Good morning");
