直接设置XML Layout：

<TextView

android:id="@+id/text_view"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginLeft="20sp"

android:layout_marginRight="20sp"

android:textStyle="bold"

android:background="@drawable/xq"

android:textSize="20sp" />

使用xml文件设置属性

styles.xml:

<resources>

<!--

Base application theme, dependent on API level. This theme is replaced

by AppBaseTheme from res/values-vXX/styles.xml on newer devices.

-->

<style name="AppBaseTheme" parent="android:Theme.Light">

<!--

Theme customizations available in newer API levels can go in

res/values-vXX/styles.xml, while customizations related to

backward-compatibility can go here.

-->

</style>

<!-- Application theme. -->

<style name="AppTheme" parent="AppBaseTheme">

<!-- All customizations that are NOT specific to a particular API-level can go here. -->

</style>

<style name="TextView">

<item name="android:layout_width">wrap_content</item>

<item name="android:layout_height">wrap_content</item>

<item name="android:layout_marginLeft">20sp</item>

<item name="android:textStyle">bold</item>

<item name="android:layout_marginRight">20sp</item>

<item name="android:background">@drawable/xq</item>

<item name="android:textColor">#005</item>

<item name="android:shadowColor">@android:color/black</item>

<item name="android:shadowRadius">0.5</item>

<item name="android:textSize">20sp</item>

</style>

</resources>

layout.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="horizontal">

<TextView

android:id="@+id/text_view"

style="@style/TextView"/>

</LinearLayout>

 

设置文本方法：

TextView myText = (TextView) findViewById(R.id.text_view);

        myText.setText("ccc");

 

设置背景图片方法：

TextView myText = (TextView) findViewById(R.id.text_view);

Resources resources=getBaseContext().getResources();

Drawable drawable=resources.getDrawable(R.drawable.xq1);

myText.setBackgroundDrawable(drawable);
