自定义风格的AlertDialog的样式属性 [英] Style attributes of custom styled AlertDialog

问题描述

我正在尝试对我的AlertDialog进行风格化，我已经能够通过样式和xml声明来改变大部分内容，但仍有一些问题：

I am trying to style my AlertDialog and I have been able to change most of it through styles and xml declarations... but there are still a few issues:

1. 如何将标题栏周围的区域从黑色更改为自定义颜色？


2. 如何将外部背景更改为透明（外部部分，蓝色，阴影掉落）


3. 如何更改按钮，使其不会与警报信息周围的黑色边框重叠？

这里是我在RootActivity中的功能（我的活动扩展了这一个）

here is the function I have in my RootActivity (my activities extend this one)

public static void showNoConnectionDialog(Context ctx1) {
    final Context ctx = ctx1;
    LayoutInflater factory = LayoutInflater.from(ctx);
    AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(ctx, R.style.SetdartDialog));
    builder.setView(factory.inflate(R.layout.alert_dialog, null))
    .setIcon(R.drawable.icon)
    .setCancelable(true)
    .setMessage(R.string.check_wireless_settings)
    .setTitle(R.string.no_connection)
    .setPositiveButton(R.string.myes, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            ctx.startActivity(new Intent(Settings.ACTION_WIRELESS_SETTINGS));
        }
    })
    .setNegativeButton(R.string.mno, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            return;
        }
    })
    .setOnCancelListener(new DialogInterface.OnCancelListener() {
        public void onCancel(DialogInterface dialog) {
            return;
        }
    })
    .show();
}

这里是styles.xml中的一个片段

here a snippet from styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.WhiteBackground" parent="android:Theme">
        <item name="android:windowBackground">@null</item>
        <item name="android:background">@android:color/white</item>
        <!-- Dialog attributes
        <item name="alertDialogStyle">@style/AlertDialog</item>  -->
    </style>
    <style name="SetdartDialog">
            <item name="android:background">@color/sd_blue</item> <!-- MUST HAVE with white bg-->
            <!--<item name="android:windowBackground">@color/sd_blue</item> -->
            <!--<item name="android:windowBackground">@color/transparent</item> needed with white bg ? -->
            <item name="android:windowFrame">@color/transparent</item><!-- not sure what this changes-->
            <item name="android:textColor">@android:color/black</item>
            <item name="android:windowNoTitle">true</item>
            <item name="android:textSize">10sp</item>
            <item name="android:windowIsFloating">true</item>
            <item name="android:windowContentOverlay">@color/transparent</item>
            <item name="android:windowTitleStyle">@style/setwindowTitleStyle</item>
            <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
            <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
            <item name="android:backgroundDimEnabled">true</item>
            <item name="android:gravity">center_vertical|center_horizontal</item>
        <!--<item name="android:colorBackgroundCacheHint">@android:color/white</item>-->
        </style>
        <style name="setwindowTitleStyle">
            <item name="android:textColor">@android:color/white</item>
            <item name="android:background">@color/sd_blue</item>
        </style>
</resources>

另外R.layout.alert_dialog

Also R.layout.alert_dialog

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/screen"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:orientation="vertical"
    >
    <LinearLayout
        android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:orientation="vertical">
    </LinearLayout>
</ScrollView>

推荐答案

创建具有所有这些属性的自定义布局提及。使用对话框而不是 AlertDialog ，展开您创建的布局，使用Dialog对象设置膨胀的布局。如果你没有被介绍给充气服务，做一些研究。在您充满清醒之后，请记住使用 View 对象访问的对话框的所有组件，您已使用充气创建。其余的（如点击听众）仍然需要通常的方式。干杯。我希望它有帮助。

Create your custom layout with all these attributes you've mentioned. Use Dialog instead of AlertDialog, inflate the layout you have created, use the Dialog object to set the inflated layout. If you haven't been introduced to inflating service, do some research. After you are clear with inflating, remember that all the components of the dialog you access with the View object, that you have created with the inflating. The rest (like click listeners) remains to be done on usual way. Cheers. I hope it helps.
