java-如何创建自定义ProgressBar
作者:互联网
编辑:
问题1)已解决.但是我仍然无法更改ProgressBar的颜色.我尝试使用自己的主题(请参见下面的代码).
我希望我的ProgressBar看起来像下面的图像.我已经在ListView上方创建了一个ProgressBar.我在RelativeLayout中使用ListView,ProgressBar和两个TextView.
我的问题:
1.) How can I align the
TextViews
above theProgressBar
in the way shown below?
2.) How can I set the Color of theProgressBar
itself and the Background Color of theProgressBar
?
MainActivity.xml
<ProgressBar
android:id="@+id/progressBar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/progressBarText"
android:progress="0"
android:max="100"
android:paddingTop="0dp"
android:paddingBottom="10dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:theme="@style/progressBarTheme"
style="@style/Widget.AppCompat.ProgressBar.Horizontal"/>
styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">@android:color/holo_green_dark</item>
</style>
<style name="progressBarTheme" parent="@style/Theme.AppCompat">
<item name="colorAccent">@color/myRedColor</item>
</style>
</resources>
解决方法:
1.) How can I align the TextViews above the ProgressBar in the way shown below?
尝试这个:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal">
<ProgressBar
android:id="@+id/progressCircle"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
<TextView
android:id="@+id/txtvStatusCircle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@id/progressCircle"
android:layout_alignParentStart="true"
android:text="Daily Progress"
android:textSize="18sp" />
<TextView
android:id="@+id/txtPercent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@id/progressCircle"
android:layout_alignParentEnd="true"
android:text="0 %"
android:textSize="18sp" />
</RelativeLayout>
2.) How can I set the Color of the
ProgressBar
itself and the Background Color of theProgressBar
?
在您的styles.xml中:
<style name="progressBarBlue" parent="@style/Theme.AppCompat">
<item name="colorAccent">@color/myBlueColor</item>
</style>
然后在xml中设置为ProgressBar主题:
<ProgressBar
...
android:theme="@style/progressBarBlue" />
关于ProgressBar本身,无论您为样式中的AccentColor选择什么,都将为ProgressBar设置.因此更改颜色:
<item name="colorAccent">@color/colorAccent/item>
会成功的.
