How to draw a drawable onto a canvas?
0
I have made a class SwipeController class which extends Callback.
onChildDraw is as follows:
@Override
public void onChildDraw(Canvas c,
RecyclerView recyclerView,
RecyclerView.ViewHolder viewHolder,
float dX, float dY,
int actionState, boolean isCurrentlyActive) {
drawButtons(c, viewHolder);
if (actionState == ACTION_STATE_SWIPE) {
setTouchListener(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
}
super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
}
drawButtons method is as follows:
private void drawButtons(Canvas c, RecyclerView.ViewHolder viewHolder) {
float buttonWidthWithoutPadding = buttonWidth - 20;
float corners = 2;
View itemView = viewHolder.itemView;
Paint p = new Paint();
RectF leftButton = new RectF(itemView.getLeft(), itemView.getTop(), itemView.getLeft() + buttonWidthWithoutPadding, itemView.getBottom());
p.setColor(Color.BLUE);
c.drawRoundRect(leftButton, corners, corners, p);
drawText("EDIT", c, leftButton, p);
RectF rightButton = new RectF(itemView.getRight() - buttonWidthWithoutPadding, itemView.getTop()+20, itemView.getRight()-20, itemView.getBottom()-20);
p.setColor(Color.RED);
c.drawRoundRect(rightButton, corners, corners, p);
drawText("DELETE", c, rightButton, p);
buttonInstance = null;
if (buttonShowedState == ButtonsState.LEFT_VISIBLE) {
buttonInstance = leftButton;
}
else if (buttonShowedState == ButtonsState.RIGHT_VISIBLE) {
buttonInstance = rightButton;
}
}
Now this works fine as expected. But I want to use drawable images instead of just simple text on the buttons. Is there a way to do it? Any help will be appreciated.

The thing is its kind of silly. I have seen the documentation also. I actually don't know how to reach to my drawable files.Drawableneedsandroid.graphics.drawable. AndR.drawable.some_drawablegivesint. I am using this swipe thing for the very first time.

Drawable needs android.graphics.drawable. And R.drawable.some_drawable gives int. I am using this swipe thing for the very first time.– Ashish Yadav
