更改带有边框的按钮的背景 [英] Change background of button with border

问题描述

我创建了一个带边框的按钮:

I have created a button with border:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >

    <solid android:color="#FFFFFFFF" />

    <stroke
        android:width="1dp"
        android:color="#FFCCCCCC" />
</shape>

和

<Button
        android:text="@null"
        android:stateListAnimator="@null"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:id="@+id/colorButton"
        android:background="@drawable/button_border" />

现在，我以编程方式更改背景的颜色.问题是，一旦更改背景，边框就会被删除.有没有一种方法可以更改按钮的背景色并保留边框?

Now I change the color of the background programmatically. The problem is that the border gets removed as soon as I change the background. Is there a way to change to background color of the button and keeping the border?

推荐答案

尝试一下，

    Button colorButton = (Button) findViewById(R.id.colorButton);
    GradientDrawable background = (GradientDrawable) colorButton.getBackground();
    background.setColor(getResources().getColor(R.color.some_color));
