I have created a custom AlertDialog with rounded corners using onDraw of LinearLayout as below,
public class RoundedLinearLayout extends LinearLayout {
private Paint drawPaint;
private Paint roundPaint;
private int mCornerRadius = 100;
private RectF bounds;
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public RoundedLinearLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
onInit();
}
public RoundedLinearLayout(Context context, AttributeSet attrs) {
super(context, attrs);
onInit();
}
public RoundedLinearLayout(Context context) {
super(context);
onInit();
}
protected void onInit() {
drawPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
drawPaint.setColor(0xffffffff);
drawPaint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
roundPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
roundPaint.setColor(0xffffffff);
setWillNotDraw(false);
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
if (w != oldw && h != oldh) {
bounds = new RectF(0, 0, w, h);
}
}
@Override
protected void dispatchDraw(Canvas canvas) {
Bitmap bitmap = Bitmap.createBitmap((int) bounds.width(), (int) bounds.height(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(bitmap);
super.dispatchDraw(c);
BitmapShader shader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
Paint paint = new Paint();
paint.setAntiAlias(true);
paint.setShader(shader);
canvas.drawRoundRect(bounds, mCornerRadius, mCornerRadius, paint);
}
}
And then I added transparency by getWindow() and setting window.alpha = 0.5f .
The resulting dialog is,
I want to remove those corner white background. I have searched 100s of questions here and no answer could get me the perfect rounded corner alert dialog. Any help would be appreciated!
