Android TextView 初步学习

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);
