Android 按钮可绘制色调 [英] Android Button Drawable Tint

问题描述

是否可以为 Android 按钮中的 drawableLeft 着色?我有一个黑色的可绘制对象，我想将其染成白色.我知道如何使用图像视图(左侧的图像)来实现这一点，但我想使用默认的 android 按钮来实现.

Is it possible to tint the drawableLeft in an android button? I have a black drawable I'd like to tint white. I know how to achieve this with an image view (image on the left) but I want to do this with the default android button.

我的源代码:

<Button android:layout_height="wrap_content"
        android:layout_width="0dp"
        android:layout_weight="1"
        android:text="@string/drawer_quizzes"
        android:backgroundTint="@color/md_light_green_500"
        android:stateListAnimator="@null"
        android:textColor="#fff"
        android:textSize="12dp"
        android:fontFamily="sans-serif"
        android:drawableLeft="@drawable/ic_action_landscape"
        android:gravity="left|center_vertical"
        android:drawablePadding="8dp"
        />

有没有办法给按钮着色?或者有没有自定义view的方法来实现这个效果?

Is there any way to tint the button? Or is there a custom view method to achieve this effect?

推荐答案

您可以使用此方法实现为按钮上的 drawableleft 着色:

You can achieve coloring the drawableleft on a button with this method:

第 1 步:如下图创建一个以位图为父元素的可绘制资源文件并命名作为drawable文件夹下的ic_action_landscape.xml

Step 1: Create a drawable resource file with bitmap as parent element as shown below and name it as ic_action_landscape.xml under the drawable folder

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@android:drawable/ic_btn_speak_now"
    android:tint="@color/white" />

第 2 步:在您的布局中创建您的 Button 控件，如下所示

Step 2: Create your Button control in your layout as below

<Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:backgroundTint="@color/md_light_green_500"
        android:drawableLeft="@drawable/ic_action_landscape"
        android:drawablePadding="8dp"
        android:fontFamily="sans-serif"
        android:gravity="left|center_vertical"
        android:stateListAnimator="@null"
        android:text="@string/drawer_quizzes"
        android:textColor="#fff"
        android:textSize="12dp" />

按钮从drawable文件夹中的ic_action_landscape.xml中获取drawable，而不是@android:drawable或drawable png(s).

The button gets the drawable from the ic_action_landscape.xml from the drawable folder instead of @android:drawable or drawable png(s).

方法二:
第一步:
您甚至可以将图标添加为操作栏和选项卡图标，并将前景作为图像可以从自定义位置或剪贴画导入

Method 2:
Step 1:
You can even add the icon as a Action Bar and Tab icons with Foreground as Image that can be imported from a custom location or a Clipart

第 2 步:
在主题下拉菜单下选择自定义

Step 2:
Under Theme dropdown select Custom

第 3 步:
然后在前景色选择中选择颜色为#FFFFFF.

Step 3:
Then select the color as #FFFFFF in the Foreground color selection.

最后完成添加图像的向导，然后将drawable添加为图像.

Finally finish the wizard to add the image, then add the drawable as an image.
