[英]Is it possible to obtain the value of a variable from the activity in the layout.xml android?
[英]Is it possible that a seekbar and listview be in a layout.xml in android?
我想在layout.xml 中使用seekbar 和listview,在android 中使用Activity。 是否可以?
是的,有沒有可能,請看下面的代碼
<?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:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="This is your seek bar"
android:id="@+id/textView" />
<SeekBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/seekBar" />
<TextView
