下面是佈局文件Textview的 android:clickable="true"要設爲true
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:clickable="true"
android:id="@+id/tv_demo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="22sp" />
</LinearLayout>
