如何設置TextView
以編程方式背景爲xml/ripple?如何以編程方式設置XML波動?
XML/ripple.xml:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?android:colorFocusedHighlight">
<item android:id="@android:id/mask">
<shape android:shape="rectangle">
<solid android:color="?android:colorAccent" />
</shape>
</item>
</ripple>
我試圖text.setBackground((Drawable) context.getResources().getXml(R.xml.ripple));
但它返回了以下異常:
