Android 警报对话框背景问题 API 11+ [英] Android Alert Dialog Background Issue 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 the AlertDialog class and it does not take the standard theme. when I replaced R.style.MyTheme or android.R.style.Theme_Holo_Dialog with AlertDialog.THEME_HOLO_LIGHT the code worked just fine.

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