Android:如何自定义AlertDialog，Dialog和Spinner标题 [英] Android: How to customize AlertDialog, Dialog an Spinner titles

问题描述

我想自定义所有对话框，alertDialogs和微调框.我想更改文本的颜色和标题栏的背景.

I want to customize all dialogs, alertDialogs and spinner. I want to change the color of text and the background of the title bar.

我试图更好地解释: 我希望文本(JOLLY BAR DI ...)为白色，标题的背景(从对话框顶部到标题下方的软蓝色线条)为蓝色(#044592).

I try to explain better: I want the text (JOLLY BAR DI ...) to be white and the background of the title (from the top of the dialog to the soft-blue line below the title included) to be blue (#044592).

我该怎么办?

推荐答案

好，我几乎解决了这个问题(我在回答我自己的问题，因为它可能会帮助其他人解决与我相同的问题). 问题仍然存在于微调器，DatePickers等.

Ok, I've almost solved the problem (I'm answering my own question because it may help others with the same problem as mine). The problem remains for spinners, DatePickers etc.

对于AlertDialogs，我这样做:

For the AlertDialogs I do something like this:

AlertDialog.Builder builder = new AlertDialog.Builder(MyActivity.this, AlertDialog.THEME_HOLO_LIGHT);
//Then I do what I need with the builder (except for setTitle();
LayoutInflater inflater = getLayoutInflater();
View view=inflater.inflate(R.layout.dialog_custom_title, null);
TextView title = (TextView)view.findViewById(R.id.myTitle);
title.setText("Title I want to show");
builder.setCustomTitle(view);
AlertDialog alert = builder.create();
alert.show();

dialog_custom_titile.xml:

dialog_custom_titile.xml :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#044592" >

   <TextView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/myTitle"
        android:layout_width="fill_parent"
        android:textSize="20dp"
        android:layout_height="70dp"
        android:layout_marginLeft="25dp"
        android:paddingTop="22dp"
        android:textColor="@android:color/white"
        android:textStyle="bold" />

</RelativeLayout>

对于我想看起来像对话框的活动，我这样做是这样的: 我在Manifest.xml中声明它们，如下所示:

for the Activities that I want to look like Dialogs I do like this: I declare them in the Manifest.xml as follows:

<activity
     android:name="com.aveschini.AnotherActivity"
     android:screenOrientation="portrait"
     android:label="My Dialog"
     android:theme="@style/MyDialog"
     android:windowSoftInputMode="adjustPan" />

然后，在res/values/styles.xml文件中，我这样做:

then, in the res/values/styles.xml file I do like this:

    <style name="AppTheme" parent="android:Theme.Holo.Light" />

    <style name="MyDialog" parent="android:Theme.Holo.Light.Dialog">
        <item name="android:windowTitleStyle">@style/DialogWindowTitle</item>
    </style>

    <style name="DialogWindowTitle">
        <item name="android:textAppearance">@style/TextAppearance.DialogWindowTitle</item>
        <item name="android:background">#044592</item>
    </style>

    <style name="TextAppearance.DialogWindowTitle" parent="android:TextAppearance">
        <item name="android:textColor">@android:color/white</item>
        <item name="android:textStyle">bold</item>
        <item name="android:textSize">20sp</item>
    </style>

我仍然在标题和正文之间得到了淡蓝色的分隔线...仍在处理它. 如前所述，我仍然不知道如何处理Spinners，DatePicker等...

I still get the light blue divider between the title and the body... still working on it. As already said, I still don't know how to deal with Spinners, DatePicker, etc...

结果如下: AlertDialog:

That's the result: AlertDialog:

还有一个带有对话框外观的活动:

And an Activity with the look of a dialog:
