但是我想更改标题下显示的行的颜色;我该怎么做 注意:我不想使用自定义布局
如果要为警报对话框创建自定义布局 然后你可以像这样轻松地添加来改变颜色
<LinearLayout
android:id="@+id/DialogTitleBorder"
android:layout_width="fill_parent"
android:layout_height="1dip"
android:layout_below="@id/mExitDialogDesc"
android:background="#4BBAE3" <!--change color easily -->
>
</LinearLayout>
如果您使用的是自定义标题布局,那么您可以像alertDialog.setCustomTitle(customTitle)那样使用它代码>
示例
在UI线程上使用如下对话框:
LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
View customTitle = inflater.inflate(R.layout.customtitlebar, null);
AlertDialog.Builder d = new AlertDialog.Builder(this);
d.setCustomTitle(customTitle);
d.setMessage("Message");
d.setNeutralButton("OK", null);
d.show();
customtitlebar.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#525f67">
<ImageView
android:id="@+id/icon"
android:layout_width="40dp"
android:layout_height="40dp"
android:src="@drawable/ic_launcher"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" >
</ImageView>
<TextView
android:id="@+id/customtitlebar"
android:layout_width="match_parent"
android:layout_height="40dp"
android:textColor="#ffffff"
android:text="Title Name"
android:padding="3px"
android:textStyle="bold"
android:layout_toRightOf="@id/icon"
android:layout_alignParentTop="true"
android:gravity="center_vertical"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#ff0000"
android:layout_below="@id/icon"><!-- This is line below the title -->
</ImageView>
</RelativeLayout>
检查这是否对您有用
public void setCustomTitle (View customTitleView)
您可以从以下链接获得详细信息
CustomDialog.java
Dialog alert = new Dialog(this);
alert.requestWindowFeature(Window.FEATURE_NO_TITLE);
alert.setContentView(R.layout.title);
TextView msg = (TextView)alert.findViewById(R.id.textView1);
msg.setText("Hello Friends.\nIP address : 111.111.1.111");
alert.show();
title.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Set IP address"
android:textColor="#ff0000"
android:textAppearance="?android:attr/textAppearanceLarge" />
<ImageView
android:layout_width="fill_parent"
android:layout_height="2dp"
android:layout_marginTop="5dp"
android:background="#00ff00"
/>
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#775500"
android:textAppearance="?android:attr/textAppearanceLarge" />
不幸的是,这不是一项特别容易完成的任务,我详细介绍了如何通过查看Android使用的父样式、创建新图像以及基于原始样式创建新样式来调整ListSeparator
的颜色。不幸的是,与列表分隔符
的样式不同,警报对话框
主题是内部的,因此不能作为父样式引用。要改变那条蓝色的小线是不容易的!因此,您需要使用自定义对话框
如果那不是你喜欢的茶<不要放弃我非常不安,因为没有简单的方法可以做到这一点,所以我在github上建立了一个小项目,用于制作快速定制的全息风格对话框(假设手机支持全息风格)您可以在此处找到该项目:
它应该可以很容易地从乏味的蓝色变成令人兴奋的橙色
该项目基本上是一个使用自定义对话框生成器的示例,在该示例中,我创建了一个自定义视图,该视图似乎符合您在原始问题中给出的IP地址示例
使用QustomDialog
,要创建标题或分隔符颜色不同的基本对话框(标题、消息),请使用以下代码:
private String HALLOWEEN_ORANGE = "#FF7F27";
QustomDialogBuilder qustomDialogBuilder = new QustomDialogBuilder(v.getContext()).
setTitle("Set IP Address").
setTitleColor(HALLOWEEN_ORANGE).
setDividerColor(HALLOWEEN_ORANGE).
setMessage("You are now entering the 10th dimension.");
qustomDialogBuilder.show();
为了添加自定义布局(例如,添加小IP地址EditText
),您需要添加
使用您设计的布局(IP示例可以在github中找到)发送给构建器。我希望这有帮助 如果使用扩展对话框,请使用:
requestWindowFeature(Window.FEATURE_NO_TITLE);
如果你不想为此建立一个“图书馆”,你可以使用这个糟糕的黑客:
((ViewGroup)((ViewGroup)getDialog().getWindow().getDecorView()).getChildAt(0)) //ie LinearLayout containing all the dialog (title, titleDivider, content)
.getChildAt(1) // ie the view titleDivider
.setBackgroundColor(getResources().getColor(R.color.yourBeautifulColor));
这是在4.x上测试和工作的;未在下测试,但如果我的记忆力良好,它应该适用于2.x和3.x继续回答:,我从@daniel smith处获得了不错的github repo,并做了一些改进:
- 改进的示例活动
- 改进的布局
- 固定
setItems
方法
- 将分隔符添加到
项目列表中
- 单击后关闭对话框
- 支持
setItems
方法中的禁用项
listItem
触摸反馈
- 可滚动对话框消息
链接:分隔颜色:
这有点像黑客,但对我来说效果很好,而且它不需要任何外部库(至少在安卓4.4上是这样)
您可以在文件中找到更多对话框的ID。例如,android:id/alertTitle
用于更改标题颜色
更新:标题颜色
更改标题颜色的黑客:
int textViewId = d.getContext().getResources().getIdentifier("android:id/alertTitle", null, null);
TextView tv = (TextView) d.findViewById(textViewId);
tv.setTextColor(getResources().getColor(R.color.my_color));
通过遵循,我发现标题是通过扩大布局在课堂上生成的。因此,mTitleView
的Id是title
,分隔符的Id是titleDivider
我们可以通过android.R.Id.title
访问title
的Id
并通过Resources.getSystem().getIdentifier(“titleDivider”、“Id”、“android”)访问titleDivider的Id
代码>
我用来更改标题方向和颜色的最后一个代码是:
TextView mTitle = (TextView)findViewById(android.R.id.title);
mTitle.setGravity(Gravity.RIGHT|Gravity.CENTER_VERTICAL);
int x = Resources.getSystem().getIdentifier("titleDivider","id", "android");
View titleDivider = findViewById(x);
titleDivider.setBackgroundColor(getContext().getResources().getColor(R.color.some_color));
这将设置标题、图标和分隔符的颜色。绑定到任何新的Android版本进行更改
public static void colorAlertDialogTitle(AlertDialog dialog, int color) {
int dividerId = dialog.getContext().getResources().getIdentifier("android:id/titleDivider", null, null);
if (dividerId != 0) {
View divider = dialog.findViewById(dividerId);
divider.setBackgroundColor(color);
}
int textViewId = dialog.getContext().getResources().getIdentifier("android:id/alertTitle", null, null);
if (textViewId != 0) {
TextView tv = (TextView) dialog.findViewById(textViewId);
tv.setTextColor(color);
}
int iconId = dialog.getContext().getResources().getIdentifier("android:id/icon", null, null);
if (iconId != 0) {
ImageView icon = (ImageView) dialog.findViewById(iconId);
icon.setColorFilter(color);
}
}
在调用此方法之前,请记住调用dialog.show()。下面是另一个解决方案(基于建议的答案),它可以在一个类中处理对话框的样式,而无需担心更改样式时对话框的状态-对话框可以已经显示或刚刚初始化
用法示例:
AlertDialog.Builder builder = new AlertDialog.Builder(context);
AlertDialog dialog = builder.create(); //or builder.show()
DialogViewDecorator.decorate(dialog, android.R.color.holo_red_light); //can also set the defaut color in the class
实施:
public class DialogViewDecorator {
private static final
@ColorRes int DEFAULT_TITLE_DIVIDER_COLOR = android.R.color.holo_orange_light;
public static void decorate(Dialog dialog) {
decorate(dialog, DEFAULT_TITLE_DIVIDER_COLOR);
}
/**

* <p/>

public static <T extends OnDecoratedDialogShownListener> void decorate(Dialog dialog, int titleDividerColor, T OnShowListener) {
if (dialog == null || titleDividerColor <= 0) { return; }
