NumberPicker没有显示数字

我正在尝试在其中创建AlertDialog NumberPicker 但是它只显示两个分隔符而没有文本。

请参阅 http://imageshack.com/a/img673/8149/aWHQfj.png

我正在使用:

android:minSdkVersion="11"
android:targetSdkVersion="19"

    private void showInputDialog() {
    Context context = getActivity();
    RelativeLayout linearLayout = new RelativeLayout(context);
    final NumberPicker numberPicker = new NumberPicker(context);

    numberPicker.setMaxValue(1);
    numberPicker.setMinValue(100);
    numberPicker.setWrapSelectorWheel(false);

    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(50, 50);
    RelativeLayout.LayoutParams numPicerParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    numPicerParams.addRule(RelativeLayout.CENTER_HORIZONTAL);

    linearLayout.setLayoutParams(params);
    linearLayout.addView(numberPicker,numPicerParams);

    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
    alertDialogBuilder.setTitle("Number of strokes");
    alertDialogBuilder.setView(linearLayout);
    alertDialogBuilder
            .setCancelable(false)
            .setPositiveButton("Ok",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            int score = numberPicker.getValue();

                            if (mRows != null) {
                                if (mClickedColIndex > 10) mClickedColIndex -= 1;

                                mClickedPlayer.setManualScore(mClickedColIndex, score);
                            } else {
                                if (mClickedRowIndex > 10) mClickedRowIndex -= 1;

                                mClickedPlayer.setManualScore(mClickedRowIndex, score);
                            }

                            mClickedText.setText(Integer.toString(score));

                            setupScorecard();
                        }
                    })
            .setNegativeButton("Cancel",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,
                                            int id) {
                            dialog.cancel();
                        }
                    });

    AlertDialog alertDialog = alertDialogBuilder.create();
    alertDialog.show();
}

我已就该主题进行过多次搜索,但我还没有找到任何有效的解决方案..

还有什么我不能设置的:android:numberPickerStyle在styles.xml中。

有人对此有任何想法吗?

1 个答案:

答案 0 :(得分:1)

改变这个:

numberPicker.setMaxValue(1);
numberPicker.setMinValue(100);

用这个:

numberPicker.setMaxValue(100);
numberPicker.setMinValue(1);

最小值不能高于最大值。
