AlertDialog.Builder项目背景颜色 [英] AlertDialog.Builder item background color

问题描述

我试图使这三个项目这AlertDialog绿色。问题在于目前绿色背景出现的警报后面和两个项目的不显示绿色。我目前设置AlertDialog的风格与此code：

I'm trying to make the three items of this AlertDialog green. The problem is that currently a green background appears behind the alert, and two of the items do not appear green. I currently set the style of the AlertDialog with this code:

final AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(getActivity(), R.style.ListRow));

在我styles.xml，我有这样的风格：

In my styles.xml, I have this style:

<style name="ListRow">
    <item name="android:background">@color/forest_green</item>
    <item name="android:textSize">18sp</item>
    <item name="android:textColor">@color/dialog_text</item>
</style>

推荐答案

这个工作给我。他们都有后台。

this worked to me. all of them have background.

final AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.ListRow));

builder.setIcon(android.R.drawable.ic_dialog_info).setTitle("welcome")
        .setMessage("...")
        .setPositiveButton("login", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which)
            {
                Intent intent = new Intent(HomeActivity.this, LoginActivity.class);
                startActivity(intent);
            }
        }).setNegativeButton("register", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which)
            {
                Intent intent = new Intent(getApplicationContext(),RegisterActivity.class);
                startActivity(intent);
            }
        }).show();
