A simple lightweight Android custom-view that supports a hide and show animation to a user specified position, as well as dragging. Alpha version - still under development.
Features:
- Animation between two positions (hide / show)
- Dragging and Dropping
- Fully customizable
Simply copy the HideShowDragView.java file into your project.
Create a CustomView that extends HideShowDragView with the constructor you need
public class CustomView extends HideShowDragView {
public CustomView(Context context) {
super(context);
init();
}
public CustomView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
private void init() {
// e.g. inflate a layout
addView(LayoutInflater.from(context).inflate(R.layout.custom_layout, null));
}
// ...
}Define your CustomView in .xml (supported container layouts are FrameLayout, RelativeLayout and LinearLayout)
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<your.package.CustomView
android:id="@+id/customView"
android:layout_width="90dp"
android:layout_height="90dp" >
</your.package.CustomView>
</FrameLayout>Initialize it from .xml (when defined in .xml):
CustomView hideShowView = (CustomView) findViewById(R.id.customView);Initialize a new CustomView:
CustomView hideShowView = new CustomView(Context);Inside your Activity or Fragment, use the HideShowDragListener to react to state changes and setup all parameters for your View:
public class YourActivity extemds Activity implements HideShowDragListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
// get the customview
CustomView hideShowView = (CustomView) findViewById(R.id.customView);
hideShowView.setHideShowListener(this);
// alternative 1: set the position to which the view should animate from its current position
hideShowView.setPosition(500, 500);
// OR:
// alternative 2: set the positions between the view should animate
hideShowView.setPositions(0, 0, 500, 500);
// setup other stuff ...
hideShowView.makeInvisibleOnHide(false);
hideShowView.setDragEnabled(true);
}
@Override
public void onHide(HideShowDragView v, float curX, float curY) {
}
@Override
public void onShow(HideShowDragView v, float curX, float curY) {
}
@Override
public void onDragStart(HideShowDragView v, float startX, float startY) {
}
@Override
public void onDragFinished(HideShowDragView v, float stopX, float stopY) {
}
}
