Android ContentViews

Android ContentViews Tutorial.

Types of Android ContentViews

Let's look at some examples.

AppCompatTextView is basically a TextView which provides support to older version of the android platform with compatible features of a TextView.

Whenever you use a TextView, android may automatically use the AppCompatTextView.

This is if your project has the necessary support library dependencies.

AppCompatTextView resides in the package.


This class derives from TextView:

public class AppCompatTextView extends TextView{}

Given that it derives from android.widget.TextView, this class inherits TextView's XML attributes. Some of these attributes are inherited by TextView itself from the base View class.

MarqueeView is a custom slider view that can slide vertically and horizontally.

Android TextView is a User interface widget that displays basic texts.

In almost every Graphical User Interface toolkit out there, a component or control for displaying text is there. Be it the Label in Windows Forms or the JLabel in Swing.

This is because we mostly communicate via texts and these texts have to be rendered. Well the textview renders them in Android.

TextViews and labels are normally considered basic and are easy to work with.

In android textviews are actually editable though by default this is disabled. Instead it's subclass the EditText on the other hand allows for editing.

TextView as a class resides in the android.widget package.

package android.widget;

TextView derives from android.view.View class and implements import android.view.ViewTreeObserver.OnPreDrawListener.

public class TextView extends View implements OnPreDrawListener {}

android.widget.TextView is a class used to render texts.

java.lang.StringBuilder on the other hand allows for creation of modifiable string of characters. StringBuilder is the replacemnet for StringBuffer class for non-concurrent use.

In this example we'll see how to:

  • Create a StringBuilder with multiple items.
  • Render the StringBuilder items in a TextView line by line.

For this example we don't need any XML layout. Instead we create and set an android.view.View object as our contentView for our activity.

Let's go.
