Android: colorPicker setButtonOkText 无效

Question

我有颜色选择器，但我需要更改文本 setButtonOkText(R.string.accept) 或 setButtonCancelText(R.string.cancel) 但不工作只有颜色选择器使用默认确定并取消可以改变背景托盘颜色吗？或为 ok 取消文本设置字体？

  <resources>
    <string name="cancel">Close</string>
    <string name="accept">Accept</string>
    </resources>

        val colorPicker=ColorPickerDialog.Builder()
            .setInitialColor(Color.BLACK)
            .setColorModel(ColorModel.HSV)
            .setColorModelSwitchEnabled(true)
            .setButtonOkText(R.string.accept)
            .setButtonCancelText(R.string.cansel)
            .onColorSelected { color: Int ->

            }
            .create()
        colorPicker.show(supportFragmentManager, "color_picker")

不幸的是，这个库看起来有一个错误。

正面和负面按钮的文本永远不会设置为传入的 ID。

查看第 201 行和第 202 行，这是唯一一次拉动这 2 个按钮并且它们都没有调用 setText。 xml 表明它们被硬编码为默认字符串。

幸运的是这里可能有解决方法，

您需要覆盖两个类 ColorPickerView 和 ColorPickerDialog

ColorPickerView 将只需要您提供修改后的构造函数。称之为 FixedColorPickerView

constructor(
    context: Context,
    actionOkRes: Int,
    actionCancelRes: Int,
    @ColorInt initialColor: Int = Color.DKGRAY,
    colorModel: ColorModel,
    colorModelSwitchEnabled: Boolean,
    onSwitchColorModelListener: OnSwitchColorModelListener? = null,
) : super(context,
          actionOkRes,
          actionCancelRes,
          initialColor,
          colorModel,
          colorModelSwitchEnabled,
          onSwitchColorModelListener) {
            //Your constructor will simply grab the buttons and set their texts 
            //after the real constructor has inited view.
            val positiveButton = findViewById<Button>(R.id.positive_button)
            val negativeButton = findViewById<Button>(R.id.negative_button)
            positiveButton.setText(actionOkRes)
            negativeButton.setText(actionCancelRes)
}

ColorPickerDialog 你需要覆盖 2 个方法

onCreateDialog 替换ColorPickerView 其创建。

onSaveInstanceState 以避免 NPE 由于引用旧的 ColorPickerView

class FixedColorPickerDialog : ColorPickerDialog {
    var fixPickerView: ColorPickerView by Delegates.notNull()

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        val bundle = savedInstanceState ?: arguments!!
        val actionOk = bundle.getInt(ACTION_OK_KEY)
        val actionCancel = bundle.getInt(ACTION_CANCEL_KEY)

        fixPickerView =
            FixedColorPickerView(
                requireContext(),
                actionOk,
                actionCancel,
                bundle.getInt(INITIAL_COLOR_KEY),
                ColorModel.fromName(bundle.getString(COLOR_MODEL_NAME_KEY)),
                bundle.getBoolean(COLOR_MODEL_SWITCH_KEY),
                onSwitchColorModelListener
            )

        fixPickerView.enableButtonBar(
            object : ColorPickerView.ButtonBarListener {
                override fun onNegativeButtonClick() = dismiss()
                override fun onPositiveButtonClick(color: Int) {
                    onSelectColorListener?.onColorSelected(color)
                    dismiss()
                }
            }
        )

        return AlertDialog.Builder(requireContext()).setView(fixPickerView).create()
    }
    override fun onSaveInstanceState(outState: Bundle) {
        val bundle =
            makeArgs(
                fixPickerView.actionOkRes,
                fixPickerView.actionCancelRes,
                fixPickerView.currentColor,
                fixPickerView.colorModel,
                fixPickerView.colorModelSwitchEnabled
            )
        outState.putAll(bundle)
        super.onSaveInstanceState(outState)
    }
}
