android垂直seekbar

㈠ android:如何将进度条(SeekBar)，竖着布局

读seekbar的源码，将方想反过来即可，在巴士上有现成的，你可以看看这个 http://www.apkbus.com/forum.php?mod=viewthread&tid=82748

㈡ Android开发如何更改SeekBar式样

改变seekbar上的按钮通过设置android:thumb属性

改变seekbar的那个条设置android:progressDrawable属性

示例

按钮图片

<shape>
<solidandroid:color="@android:color/black"/>
<sizeandroid:width="2dp"android:height="10dp"/>
</shape>

进度条图片

<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item>
		<layer-list>
			<itemandroid:id="@android:id/background">
			<shape>
			<gradient
			android:startColor="#1DDA0B"
			android:centerColor="#F5DA0B"
			android:endColor="#D10000"
			android:centerX="0.2"/>
			</shape>
			</item>
		</layer-list>
</item>
</selector>

给seekbar设置属性

<SeekBar
android:id="@+id/seek_aqi"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/tv_aqi_text"
android:padding="0dp"
android:thumb="@drawable/seek_aqi_thumb"
android:progressDrawable="@drawable/seek_aqi_bg"
android:max="500"
android:maxHeight="5dp"
android:minHeight="5dp"
android:progress="70"/>

效果

㈢ android 带节点的seekbar怎么搞

sdk里面没有提供设置成垂直的方法 要自己去实现 查看原帖>>

㈣ 求助，Android里面的seekbar怎么垂直显示

把seekbar复写了。。旋转90度就可以了。
