Android : 버튼 텍스트 및 배경색 변경

Android : 버튼 텍스트 및 배경색 변경

---

xml을 사용하여 버튼을 눌렀을 때 텍스트와 배경색을 모두 어떻게 변경할 수 있습니까?

텍스트 색상을 변경하려면 다음을 수행하십시오.

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:color="mycolor"/>
    <item android:color="mycolor2/>
</selector>

배경을 변경하려면 (드로어 블 참조가있는 선택기 / 항목에서 사용) 할 수 있습니다.

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FF0079FF" />
</shape>

하지만 어떻게 둘 다 할 수 있습니까? 내가 갖고 싶다고 해보자.

• 기본값 : 검정 텍스트 / 흰색 배경
• 누름 : 흰색 텍스트 / 파란색 배경

편집 : 대답

배경색과 텍스트 색상이 별도로 관리되는 것을 완전히 잊었으므로 다음과 같이했습니다.

<Button
    android:textColor="@color/filtersbuttoncolors"
    android:background="@drawable/mybackgroundcolors" />

mybackgroundcolors.xml에서 배경을 관리하고 filtersbuttoncolors.xml에서 텍스트 색상을 관리합니다. 두 XML 파일 모두에서 상태 (눌림, 선택됨, 기본값)를 관리합니다.

다음은 기본적으로 흰색, 눌렀을 때 검은 색으로 표시되는 드로어 블의 예입니다.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape>
            <solid
                android:color="#1E669B"/>
            <stroke
                android:width="2dp"
                android:color="#1B5E91"/>
            <corners
                android:radius="6dp"/>
            <padding
                android:bottom="10dp"
                android:left="10dp"
                android:right="10dp"
                android:top="10dp"/>
        </shape>

    </item>
    <item>
        <shape>
            <gradient
                android:angle="270"
                android:endColor="#1E669B"
                android:startColor="#1E669B"/>
            <stroke
                android:width="4dp"
                android:color="#1B5E91"/>
            <corners
                android:radius="7dp"/>
            <padding
                android:bottom="10dp"
                android:left="10dp"
                android:right="10dp"
                android:top="10dp"/>
        </shape>
    </item>
</selector>

API 레벨 21부터 다음을 사용할 수 있습니다.

android:backgroundTint="@android:color/white"

XML에 이것을 추가하기 만하면됩니다.

I think doing this way is much simpler:

button.setBackgroundColor(Color.BLACK);

And you need to import android.graphics.Color; not: import android.R.color;

Or you can just write the 4-byte hex code (not 3-byte) 0xFF000000 where the first byte is setting the alpha.

add below line in styles.xml

<style name="AppTheme.Gray" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorButtonNormal">@color/colorGray</item>
    </style>

in button, add android:theme="@style/AppTheme.Gray", example:

<Button
            android:theme="@style/AppTheme.Gray"
            android:textColor="@color/colorWhite"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@android:string/cancel"/>

Just complementing @Jonsmoke's answer.

For API level 21 and above you can use :

android:backgroundTint="@android:color/white"

in XML for the button layout.

For API level below 21 use an AppCompatButton using app namespace instead of android for backgroundTint.

For example:

<android.support.v7.widget.AppCompatButton
    android:id="@+id/my_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="My Button"
    app:backgroundTint="@android:color/white" />

When you create an App, a file called styles.xml will be created in your res/values folder. If you change the styles, you can change the background, text color, etc for all your layouts. That way you don’t have to go into each individual layout and change the it manually.

styles.xml:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.AppBaseTheme" parent="@android:style/Theme.Light">
    <item name="android:editTextColor">#295055</item> 
    <item name="android:textColorPrimary">#295055</item>
    <item name="android:textColorSecondary">#295055</item>
    <item name="android:textColorTertiary">#295055</item>
    <item name="android:textColorPrimaryInverse">#295055</item>
    <item name="android:textColorSecondaryInverse">#295055</item>
    <item name="android:textColorTertiaryInverse">#295055</item>

     <item name="android:windowBackground">@drawable/custom_background</item>        
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

parent="@android:style/Theme.Light" is Google’s native colors. Here is a reference of what the native styles are: https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml

name="Theme.AppBaseTheme" means that you are creating a style that inherits all the styles from parent="@android:style/Theme.Light". This part you can ignore unless you want to inherit from AppBaseTheme again. = <style name="AppTheme" parent="AppBaseTheme">

@drawable/custom_background is a custom image I put in the drawable’s folder. It is a 300x300 png image.

#295055 is a dark blue color.

My code changes the background and text color. For Button text, please look through Google’s native stlyes (the link I gave u above).

Then in Android Manifest, remember to include the code:

<application
android:theme="@style/Theme.AppBaseTheme">
