在Android中设置背景颜色并使用Drawable作为背景 [英] Set background color and use Drawable as background in Android

问题描述

此代码用于动态创建 Button.问题是我想设置背景颜色并设置背景Drawables.

This code is used to create a Button dynamically. The problem is that I want to set background color and also set a background Drawables.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <stroke android:width="1px" android:color="#696969"/>
</shape>

这是我想设置按钮背景颜色的类，然后我想使用我的 Drawable.

This is the class I want to set the background color of a Button and then I want use my Drawable.

Button btnTag = new Button(alltable.this);
btnTag.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, 
                       LinearLayout.LayoutParams.WRAP_CONTENT));
try {
    btnTag.setWidth(130);
    btnTag.setBackground(getResources().getDrawable(R.color.blue));

} catch (Exception e){
    e.printStackTrace();
}

推荐答案

在 drawable(如 files_bg.xml)文件夹中创建一个资源并将其设置为布局背景.

Create a resource in drawable (like files_bg.xml) folder and set it as background for layout.

在图层列表中使用两项，一项用于形状纯色，另一项用于位图.

Use two item in layer list, one for solid color in shape and other one bitmap.

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/totalFilesBgColor" />
        </shape>
    </item>
    <item>
        <bitmap
            android:src="@drawable/bg_icon"
            android:tileMode="disabled" />
    </item>
</layer-list> 

现在将 drawable 设置为布局中的背景或您使用它的任何地方.

and now set drawable as background in layout or wherever you are using it.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/files_bg">
</LinearLayout>
