android imagebutton with a selected state


android imagebutton with a selected state  using -'android,button,imagebutton'

If I was using an ImageButton with a selector for its background, is there a state I can change which will make it change its appearance? Right now I can get it to change images when pressed, but there seems to be no "highlighted" or "selected" or similar state which lets me toggle its appearance at will.

Here's my XML; it only changes appearance when pressed.

 <selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/map_toolbar_details_selected" />
<item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/map_toolbar_details_selected" />
<item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/map_toolbar_details_selected" />
<item android:drawable="@drawable/map_toolbar_details" />

This works for me:


" rel="nofollow" target="_blank">http://schemas.android.com/apk/res/android">
    
    
    
 

And then in java:

//assign the image in code (or you can do this in your layout xml with the src attribute)
imageButton.setImageDrawable(getBaseContext().getResources().getDrawable(R.drawable....));

//set the click listener
imageButton.setOnClickListener(new OnClickListener() {

    public void onClick(View button) {
        //Set the button's appearance
        button.setSelected(!button.isSelected());

        if (button.isSelected()) {
            //Handle selected state change
        } else {
            //Handle de-select state change
        }

    }

});

For smooth transition you can also mention animation time:

The best way to do this without more images :

public static void buttonEffect(View button){
    button.setOnTouchListener(new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN: {
                    v.getBackground().setColorFilter(0xe0f47521,PorterDuff.Mode.SRC_ATOP);
                    v.invalidate();
                    break;
                }
                case MotionEvent.ACTION_UP: {
                    v.getBackground().clearColorFilter();
                    v.invalidate();
                    break;
                }
            }
            return false;
        }
    });
}

ToggleImageButton which implements Checkable interface and supports OnCheckedChangeListener and android:checked xml attribute:

public class ToggleImageButton extends ImageButton implements Checkable {
    private OnCheckedChangeListener onCheckedChangeListener;

    public ToggleImageButton(Context context) {
        super(context);
    }

    public ToggleImageButton(Context context, AttributeSet attrs) {
        super(context, attrs);
        setChecked(attrs);
    }

    public ToggleImageButton(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        setChecked(attrs);
    }

    private void setChecked(AttributeSet attrs) {
        TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.ToggleImageButton);
        setChecked(a.getBoolean(R.styleable.ToggleImageButton_android_checked, false));
        a.recycle();
    }

    @Override
    public boolean isChecked() {
        return isSelected();
    }

    @Override
    public void setChecked(boolean checked) {
        setSelected(checked);

        if (onCheckedChangeListener != null) {
            onCheckedChangeListener.onCheckedChanged(this, checked);
        }
    }

    @Override
    public void toggle() {
        setChecked(!isChecked());
    }

    @Override
    public boolean performClick() {
        toggle();
        return super.performClick();
    }

    public OnCheckedChangeListener getOnCheckedChangeListener() {
        return onCheckedChangeListener;
    }

    public void setOnCheckedChangeListener(OnCheckedChangeListener onCheckedChangeListener) {
        this.onCheckedChangeListener = onCheckedChangeListener;
    }

    public static interface OnCheckedChangeListener {
        public void onCheckedChanged(ToggleImageButton buttonView, boolean isChecked);
    }
}
