I have no idea how to fix the errors, I have tested many solutions but nothing changed. I will be happy for your help.

CodePudding user response：

In the StickerView file:

  1. Remove the StickerView(Context context) constructor
  2. Put the initialization code also in the StickerView(Context context, AttributeSet attributeSet) constructor (creating a dedicated method is a good approach) and
  3. Change this(context, attributeSet, 0) to super(context, attributeSet)
public StickerView(Context context, AttributeSet attributeSet) {
    super(context, attributeSet);
    setup();
}

public StickerView(Context context, AttributeSet attributeSet, int i) {
    super(context, attributeSet, i);
    setup();
}

public void setup() {
    this.mOldDistance = 0.0f;
    this.mOldRotation = 0.0f;
    this.mCurrentMode = ActionMode.NONE;
    this.mTouchSlop = 3;
    Paint paint = new Paint();
    this.mBorderPaint = paint;
    paint.setAntiAlias(true);
    this.mBorderPaint.setColor(-16777216);
    this.mBorderPaint.setAlpha(128);
    this.mSizeMatrix = new Matrix();
    this.mDownMatrix = new Matrix();
    this.mMoveMatrix = new Matrix();
    this.mStickerRect = new RectF();
     **//Below line #129 the compiler select BitmapStickerIcon**
    this.mDeleteIcon = new BitmapStickerIcon(ContextCompat.getDrawable(getContext(), R.drawable.ic_close_white_18dp));
    this.mZoomIcon = new BitmapStickerIcon(ContextCompat.getDrawable(getContext(), R.drawable.ic_scale_white_18dp));
