public class Button
extends TextView

java.lang.Object
↳	android.view.View
	↳	android.widget.TextView
		↳	android.widget.Button

Known direct subclasses CompoundButton CompoundButton A button with two states, checked and unchecked.

Known indirect subclasses CheckBox, RadioButton, Switch, ToggleButton CheckBox A checkbox is a specific type of two-states button that can be either checked or unchecked.  RadioButton A radio button is a two-states button that can be either checked or unchecked.  Switch A Switch is a two-state toggle widget.  ToggleButton Displays checked/unchecked states as a button with a "light" indicator and by default accompanied with the text "ON" or "OFF".

---

A user interface element the user can tap or click to perform an action.

To display a button in an activity, add a button to the activity's layout XML file:

 <Button
     android:id="@+id/button_id"
     android:layout_height="wrap_content"
     android:layout_width="wrap_content"
     android:text="@string/self_destruct" />

To specify an action when the button is pressed, set a click listener on the button object in the corresponding activity code:

 public class MyActivity extends Activity {
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

         setContentView(R.layout.content_layout_id);

         final Button button = findViewById(R.id.button_id);
         button.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Code here executes on main thread after user presses button
             }
         });
     }
 }

The above snippet creates an instance of View.OnClickListener and wires the listener to the button using setOnClickListener(View.OnClickListener). As a result, the system executes the code you write in onClick(View) after the user presses the button.

The system executes the code in onClick on the main thread. This means your onClick code must execute quickly to avoid delaying your app's response to further user actions. See Keeping Your App Responsive for more details.

Every button is styled using the system's default button background, which is often different from one version of the platform to another. If you are not satisfied with the default button style, you can customize it. For more details and code samples, see the Styling Your Button guide.

For all XML style attributes available on Button see Button Attributes, TextView Attributes, View Attributes. See the Styles and Themes guide to learn how to implement and organize overrides to style-related attributes.

The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer. In the rare cases where caching layers are useful, such as for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a Canvas from either a Bitmap or Picture and call draw(android.graphics.Canvas) on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as Config.HARDWARE bitmaps, real-time shadows, and outline clipping.

Public constructors

Button

Added in API level 1

public Button (Context context)

Simple constructor to use when creating a button from code.

Parameters
context	Context: The Context the Button is running in, through which it can access the current theme, resources, etc.

See also:

• Button(Context, AttributeSet)

Button

Added in API level 1

public Button (Context context, 
                AttributeSet attrs)

LayoutInflater calls this constructor when inflating a Button from XML. The attributes defined by the current theme's android:buttonStyle override base view attributes. You typically do not call this constructor to create your own button instance in code. However, you must override this constructor when creating custom views.

Parameters
context	Context: The Context the view is running in, through which it can access the current theme, resources, etc.
attrs	AttributeSet: The attributes of the XML Button tag being used to inflate the view.

public Button (Context context, 
                AttributeSet attrs, 
                int defStyleAttr)

This constructor allows a Button subclass to use its own class-specific base style from a theme attribute when inflating. The attributes defined by the current theme's defStyleAttr override base view attributes.

For Button's base view attributes see Button Attributes, TextView Attributes, View Attributes.

Parameters
context	Context: The Context the Button is running in, through which it can access the current theme, resources, etc.
attrs	AttributeSet: The attributes of the XML Button tag that is inflating the view.
defStyleAttr	int: The resource identifier of an attribute in the current theme whose value is the the resource id of a style. The specified style\u2019s attribute values serve as default values for the button. Set this parameter to 0 to avoid use of default values.

Button

Added in API level 21

public Button (Context context, 
                AttributeSet attrs, 
                int defStyleAttr, 
                int defStyleRes)

This constructor allows a Button subclass to use its own class-specific base style from either a theme attribute or style resource when inflating. To see how the final value of a particular attribute is resolved based on your inputs to this constructor, see View.View(Context, AttributeSet, int, int).

Parameters
context	Context: The Context the Button is running in, through which it can access the current theme, resources, etc.
attrs	AttributeSet: The attributes of the XML Button tag that is inflating the view.
defStyleAttr	int: The resource identifier of an attribute in the current theme whose value is the the resource id of a style. The specified style\u2019s attribute values serve as default values for the button. Set this parameter to 0 to avoid use of default values.
defStyleRes	int: The identifier of a style resource that supplies default values for the button, used only if defStyleAttr is 0 or cannot be found in the theme. Set this parameter to 0 to avoid use of default values.

Public methods

getAccessibilityClassName

Added in API level 23

public CharSequence getAccessibilityClassName ()

Return the class name of this object to be used for accessibility purposes. Subclasses should only override this if they are implementing something that should be seen as a completely new class of view when used by accessibility, unrelated to the class it is deriving from. This is used to fill in AccessibilityNodeInfo.setClassName.

Returns
CharSequence

onResolvePointerIcon

Added in API level 24

public PointerIcon onResolvePointerIcon (MotionEvent event, 
                int pointerIndex)

Resolve the pointer icon that should be used for specified pointer in the motion event. The default implementation will resolve the pointer icon to one set using setPointerIcon(android.view.PointerIcon) for mouse devices. Subclasses may override this to customize the icon for the given pointer. For example, the pointer icon for a stylus pointer can be resolved in the following way:

 @Override
 public PointerIcon onResolvePointerIcon(MotionEvent event, int pointerIndex) {
     final int toolType = event.getToolType(pointerIndex);
     if (!event.isFromSource(InputDevice.SOURCE_MOUSE)
             && event.isFromSource(InputDevice.SOURCE_STYLUS)
             && (toolType == MotionEvent.TOOL_TYPE_STYLUS
                     || toolType == MotionEvent.TOOL_TYPE_ERASER)) {
         // Show this pointer icon only if this pointer is a stylus.
         return PointerIcon.getSystemIcon(mContext, PointerIcon.TYPE_WAIT);
     }
     // Use the default logic for determining the pointer icon for other non-stylus pointers,
     // like for the mouse cursor.
     return super.onResolvePointerIcon(event, pointerIndex);
 }
 

Parameters
event	MotionEvent: The MotionEvent that requires a pointer icon to be resolved for one of pointers.
pointerIndex	int: The index of the pointer in event for which to retrieve the PointerIcon. This will be between 0 and MotionEvent#getPointerCount().

Returns
PointerIcon	the pointer icon to use for specified pointer, or null if a pointer icon is not specified and the default icon should be used.
