android 从 EditText 更改图标的颜色

Question

我有以下 EditText :

editText.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ic_arrow_bottom_right_black_18dp, 0);

我正在尝试使用以下方法以编程方式更改 ic_arrow_bottom_right_black_18dp 的颜色：

     protected void setEditTextDisabled(EditText editText) {
        editText.setFocusable(false);
        editText.setClickable(false);
        editText.setEnabled(false);
        editText.setTextColor(ContextCompat.getColor(getContext(), R.color.package_components_group_text_color));
        if (editText.getTag(R.id.values_list_selected_ids) == null) {
            if (editText.getTag(R.id.values_list_selected_ids) == null) {
                editText.setFocusableInTouchMode(true);
                Drawable[] d = editText.getCompoundDrawables();
                if (d.length == 4) {
                    d[2].setColorFilter(ContextCompat.getColor(getContext(), R.color.package_components_group_text_color), PorterDuff.Mode.SRC_ATOP);
                }
            }
        }
        Drawable background = editText.getBackground();

        if (background instanceof ShapeDrawable) {
//          ((ShapeDrawable)background).getPaint().setStroke(2, getResources().getColor(R.color.package_components_group_text_color));
//            ((ShapeDrawable)background).getPaint().setStroke(2, getResources().getColor(R.color.package_components_group_text_color));

        } else if (background instanceof GradientDrawable) {
            ((GradientDrawable)background).setStroke(2, getResources().getColor(R.color.package_components_group_text_color));
        } else if (background instanceof ColorDrawable) {
//            ((ColorDrawable)background).setStroke(2, getResources().getColor(R.color.package_components_group_text_color));
        }
    }

    protected void setEditTextEnabled(EditText editText) {
        editText.setEnabled(true);
        editText.setFocusable(true);
        editText.setClickable(true);
        editText.setTextColor(ContextCompat.getColor(getContext(), R.color.black));
        if (editText.getTag(R.id.values_list_selected_ids) == null) {
            editText.setFocusableInTouchMode(true);
            Drawable[] d = editText.getCompoundDrawables();
            if (d.length == 4) {
                  d[2].setColorFilter(ContextCompat.getColor(getContext(), R.color.black), PorterDuff.Mode.SRC_ATOP);
            }
        }

        Drawable background = editText.getBackground();
        if (background instanceof ShapeDrawable) {
         //   ((ShapeDrawable)background).getPaint().setColor(getResources().getColor(R.color.black));
        } else if (background instanceof GradientDrawable) {
            ((GradientDrawable)background).setStroke(2, getResources().getColor(R.color.black));
        } else if (background instanceof ColorDrawable) {
          //  ((ColorDrawable)background).setColor(getResources().getColor(R.color.black));
        }
    }

问题是当调用上述方法之一时，EditText 的可绘制右侧图标变得不可见或变白。

我附上了一张图片，右边是编辑文本的图标。

Answer 1

你可以通过这个改变颜色

EditText lineColorCode =   (EditText) findViewById(R.id.line_color_code);
int color = Color.parseColor("#AE6118"); //The color u want             
lineColorCode.setColorFilter(color);

或者你可以这样做

Drawable mDrawable = context.getResources().getDrawable(R.drawable.balloons); 
mDrawable.setColorFilter(new 
PorterDuffColorFilter(0xffff00,PorterDuff.Mode.MULTIPLY));

Answer 2

这是正确答案

Drawable ddd = getResources().getDrawable(R.drawable.ic_arrow_bottom_right_black_18dp);
Drawable drawable = DrawableCompat.wrap(ddd);

DrawableCompat.setTint(drawable, ContextCompat.getColor(getContext(), R.color.package_components_group_text_color));

editText.setCompoundDrawables(null, null, drawable, null);

Answer 3

您可以使用 Picasso 库更改图标颜色而不是背景颜色。如果您可以将图标作为 ImageView 获取，则可以这样做。 Picasso 是非常简单且功能最强大的库。

Picasso.with(this)
            .load(R.drawable.your_icon)
            .transform(new ColorTransformation(getResources().getColor(R.color.your_color)))
            .into(imageViewIcon);
