android - 如何更改警告对话框android中内容文本的颜色

Question

我被卡住了，我不知道该怎么做。在我的应用程序中，有一个带有包含图像和文本的 ListView 的 AlertDialog 框，但文本颜色变为白色并且不可见我想更改 ListView 中文本的颜色。

请帮忙...

fragment 如下:

  final String[] items = new String[]{"From Gallery", "From Camera"};
        final Integer[] icons = new Integer[]{R.drawable.camera_picker, R.drawable.gallery_picker};
        ListAdapter adapter = new CameraPickAdapter(StataComplaintActivity.this, items, icons);
        final AlertDialog.Builder builder = new AlertDialog.Builder(this, AlertDialog.THEME_HOLO_LIGHT);
        //AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.CustomAlertDialogTheme));

        builder.setTitle("Select Image From")
                .setAdapter(adapter, new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int item) {
                        if (item == 0) {
                            loadImageFromGallery();
                        } else if (item == 1) {
                            takePictureIntent();
                        } else {
                        }
                    }
                }).show();

CameraPickAdapter.java

public class CameraPickAdapter extends ArrayAdapter<String> {

    private List<Integer> images;

    public CameraPickAdapter(Context context, List<String> items, List<Integer> images) {
        super(context, android.R.layout.select_dialog_item, items);
        this.images = images;
    }

    public CameraPickAdapter(Context context, String[] items, Integer[] images) {
        super(context, android.R.layout.select_dialog_item, items);
        this.images = Arrays.asList(images);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
        TextView textView = (TextView) view.findViewById(android.R.id.text1);

        textView.setCompoundDrawablesWithIntrinsicBounds(images.get(position), 0, 0, 0);
        textView.setCompoundDrawablePadding(
                (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 12, getContext().getResources().getDisplayMetrics()));
        return view;
    }

}

尝试使用上下文引用为适配器中的 TextView 设置自定义或默认颜色:

private Context context;

在构造函数中初始化上下文实例:

this.context = context;

现在使用上下文引用在 getView() 中设置自定义或默认文本颜色:

textView.setTextColor(context.getResources().getColor(R.color.custom_color_name)); // custom color

或

textView.setTextColor(context.getResources().getColor(android.R.color.black)); // default color
