问题描述
我试图找出如何更改按钮左侧可绘制图标的颜色。
I am trying to figure out how to change the color of icon which is in drawable left of button.
以下是我正在使用的XML代码:
Below is the XML code I am using :
<Button
android:layout_width="wrap_content"
android:layout_height="20dp"
android:layout_toRightOf="@+id/student_images"
android:drawableLeft="@mipmap/ic_email_black_18dp"
android:text=" myemail@gmail.com "
android:layout_below="@+id/email"
android:background="#00000000"
android:layout_marginBottom="20dp"
android:fontFamily="sans-serif"
android:textColor="@color/gray_text_color"
/>
我尝试了 android:tint
但图标的颜色没有改变。我被困在这里。

推荐答案
您可以像下面这样以编程方式设置色调:
You can set tint programmatically like below:
int tintColor = ContextCompat.getColor(context, android.R.color.darker_gray);
Button button = (Button) findViewById(R.id.button);
Drawable drawable = ContextCompat.getDrawable(context, R.mipmap.ic_email_black_18dp);
drawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTint(drawable.mutate(), tintColor);
drawable.setBounds( 0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
button.setCompoundDrawables(drawable, null, null, null);
或者您可以使用库支持可绘制的着色笔
