以编程方式更改 TextInputEditText 的 HintTextColor 和光标颜色

Question

我在我的应用程序中使用 Spinner 和 TextInputEditText，我想在用户选择微调项时更改一些 EditText 功能（光标和提示文本颜色）。这是我的代码：

    private void setSpinner(){
        String [] types = {"q_a", "attention", "reminder", "explain", "important", "image", "voice"};
        TypeAdapter adapter = new TypeAdapter(getActivity(), types);
        spinner.setAdapter(adapter);
        
        int [] colors = {
                R.color.actual_purple, R.color.actual_pink, R.color.actual_orange,
                R.color.actual_carrot, R.color.actual_green,
                R.color.deep_blue_grey_flat_icon, R.color.deep_blue_grey_flat_icon
        };

        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                setTextEditor(colors[position]);
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });

    }

 @SuppressLint("NewApi")
    private void setTextEditor(int color){
        Drawable unwrappedDrawable = AppCompatResources.getDrawable(getActivity(), R.drawable.important_cursor);
        Drawable wrappedDrawable = DrawableCompat.wrap(unwrappedDrawable);
        DrawableCompat.setTint(wrappedDrawable, ContextCompat.getColor(getActivity(), color));
        pointEditor.setTextCursorDrawable(unwrappedDrawable);
        pointEditorLayout.setBoxBackgroundColor(ContextCompat.getColor(getActivity(), color));
        pointEditor.setHintTextColor(ContextCompat.getColor(getActivity(), color));
    }

我不明白为什么这不起作用。有人可以帮我吗？

Answer 1

对于 editText 尝试

pointEditor.setHintTextColor(getResources().getColor(color));

对于光标颜色，请查看此 answer

Answer 2

对于那些使用 TextInputLayout 的人，我找到了答案。只需简单地使用：

textInputLayout.setHintTextColor(ColorStateList.valueOf(your_color));
textInputLayout.setBoxStrokeColor(your_color);

对于光标：

editText.setTextCursorDrawable();
