这是我的样式代码
<style name="MyButtonStyle" parent="@android:style/Theme.Holo.Light.NoActionBar">
<item name="android:buttonStyle">@style/MyButton</item>
</style>
<style name="MyButton" parent="android:Widget.Holo.Button">
<item name="android:textSize">19sp</item>
<item name="android:layout_margin">0dip</item>
<item name="android:background">#ffcccc</item>
<item name="android:paddingLeft">8dp</item>
<item name="android:paddingRight">8dp</item>
<item name="android:textColor">#1A237E</item>
</style>
这是我使用此Style
的按钮 <Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/BSpotify"
android:id="@+id/BSpotify"
android:layout_below="@+id/tvTitle"
android:layout_centerHorizontal="true"
android:layout_marginTop="44dp"
android:onClick="BSpotify"
android:background="@style/MyButtonStyle"
android:layout_marginBottom="30dp" />
应用程序强制关闭，同时给这个布局充气......
这是我使用此布局的地方
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
title = (TextView) findViewById(R.id.tvTitle);
Typeface myTypeface = Typeface.createFromAsset(getAssets(), "myfont.ttf");
title.setTypeface(myTypeface);
}
这是我的LogCat输出

属性保存在res / values / styles.xml资源文件中。当我想创建按钮时，我可以从这个资源文件中提取它，并且只为每个按钮写一些特定的值（例如，android：id或android：text）。通过这样做，我可以使您的代码更清洁。 但我无法做到这一点，它不起作用:(
答案 0 :(得分：0)
要添加样式，您必须添加名为style =＆＃34;＆＃34;的标记。这是一个例子：
<Button
android:id="@+id/My_Button"
style="@style/stylename"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/button_content" />
在@style标签中声明您的样式名称。
希望这有帮助！
