Android 警报对话框背景问题 API 11+

问题描述

我用下面的代码创建了一个 AlertDialog.出于某种原因，我在 Honeycomb 及更高版本上获得了额外的背景(见图片).代码崩溃适用于蜂窝以下的任何内容.MyCustomDialog 只是 Theme.Dialog 的 API-11 和 Theme.Holo.Dialog 适用于 API-11 及更高版本.

I create a AlertDialog with the code below.For some reason I'm getting an extra background (see pic) on Honeycomb and above.The code crashes fine for anything below honeycomb.MyCustomDialog is simply Theme.Dialog for < API-11 and Theme.Holo.Dialog for API-11 and up.

1. 知道为什么我会得到额外的背景吗?
2. 知道为什么它会因 API < 而崩溃.11?如果我删除主题，它就可以正常工作.

更新找出问题 2 的答案.似乎构造函数 AlertDialog.Builder(Context context, int theme) 是在 API 11 中引入的.我的修复只是将行更改为:

Update figured out the answer to Question #2. Seems the constructor AlertDialog.Builder(Context context, int theme) was introduced in API 11. My fix was simply to change the line to:

final AlertDialog.Builder builder = (Integer.parseInt(android.os.Build.VERSION.SDK) < 11)? new AlertDialog.Builder(this) : new AlertDialog.Builder(this,R.style.JumpDialog);

我仍然需要关于问题 1 的帮助

I still need help with Question #1

private Dialog setupKeyBoardDialog() {
    if (mContact.getLocaleId() != -1) {
        final AlertDialog.Builder builder = new AlertDialog.Builder(this,R.style.MyCustomDialog);
        builder.setTitle("Keyboards");

        mKeyboardLayouts = new KeyboardLayoutGroup();
        mKeyboardLayouts.layoutNames = new CharSequence[(int) jni.getNumKeyLayouts()];
        mKeyboardLayouts.layoutValue = new ArrayList<Integer>();

        for (int i = 0; i < jni.getNumKeyLayouts(); i++) {
            mKeyboardLayouts.layoutNames[i] = jni.LayoutInfoForIndex(i).getName();
            mKeyboardLayouts.layoutValue.add(i, (int) jni.LayoutInfoForIndex(i).getLocale_id());
        }

        final int selectedItem = mKeyboardLayouts.layoutValue.indexOf(mContact.getLocaleId());

        builder.setSingleChoiceItems(mKeyboardLayouts.layoutNames, selectedItem, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int item) {
                mContact.setLocaleId(mKeyboardLayouts.layoutValue.get(item));
                mContactsDB.saveContact(mContact, true);

                dialog.dismiss();
                initializeSettingsList();
            }
        });

        final AlertDialog dialog = builder.create();
        dialog.setButton("Cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogBox, int arg1) {
                dialogBox.cancel();
            }
        });

        return dialog;
    }

    return null;
}

推荐答案

找到答案

1. AlertDialog 在每个主题的静态常量上都有AlertDialog 类，它不采用标准主题.当我替换了 R.style.MyTheme 或 android.R.style.Theme_Holo_Dialog使用 AlertDialog.THEME_HOLO_LIGHT 代码刚工作很好.

2. 似乎是构造函数 AlertDialog.Builder(Context context, int主题) 是在 API 11 中引入的.我的修复只是改变行至:

1. AlertDialog has it's on static constants for each theme in theAlertDialog class and it does not take the standard theme. when Ireplaced R.style.MyTheme or android.R.style.Theme_Holo_Dialogwith AlertDialog.THEME_HOLO_LIGHT the code worked justfine.

2. Seems the constructor AlertDialog.Builder(Context context, inttheme) was introduced in API 11. My fix was simply to change theline to:

final AlertDialog.Builder builder;
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
    builder = new AlertDialog.Builder(this);
} else {
    builder = new AlertDialog.Builder(this,R.style.JumpDialog);
}
