如果要查看資源,我有資源png of a house已鏈接。它基本上只是一個黑暗的主頁按鈕。更改資源顏色
我已將它包含並作爲圖像資源導入爲可繪製。
我試圖將其設置爲按鈕,但通過編程將其更改爲白色。
下面是我試圖改變顏色爲白色:
ImageButton txtbtnAccept = new ImageButton(this);
this._surveyHomeButton = txtbtnAccept;
txtbtnAccept.setId(this.generateViewId());
txtbtnAccept.setLayoutParams(new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
layoutParams = (RelativeLayout.LayoutParams) txtbtnAccept.getLayoutParams();
layoutParams.addRule(RelativeLayout.CENTER_VERTICAL, RelativeLayout.TRUE);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
layoutParams.height = 200;
layoutParams.width = 200;
txtbtnAccept.setScaleType(ImageView.ScaleType.FIT_CENTER);
txtbtnAccept.setAdjustViewBounds(true);
txtbtnAccept.setLayoutParams(layoutParams);
txtbtnAccept.setBackgroundResource(0);
txtbtnAccept.setVisibility(View.GONE);
Bitmap homeImage = BitmapFactory.decodeResource(getResources(), R.drawable.ic_action_home);
Drawable whiteImg = new BitmapDrawable(getResources(), homeImage);
whiteImg.setColorFilter(Color.WHITE, PorterDuff.Mode.MULTIPLY);
txtbtnAccept.setImageDrawable(whiteImg);
txtbtnAccept.setImageBitmap(homeImage);
任何想法,我要去哪裏錯了嗎?
