回答1:
Please make one xml file name progress.xml and put it in res/xml folder and write the below code in that xml file.
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0"
android:toDegrees="360">
<shape android:shape="ring" android:innerRadiusRatio="3"
android:thicknessRatio="8" android:useLevel="false">
<size android:width="76dip" android:height="76dip" />
<gradient android:type="sweep" android:useLevel="false"
android:startColor="#447a29"
android:endColor="#447a29"
android:angle="0"
/>
</shape>
</rotate>
after creating this xml file set your progressbars background as this xml ..
Like
<ProgressBar
android:id="@+id/ProgressBar01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background = "@xml/progress">

This is an old question, but using theme is not mentioned here. If your default theme is using AppCompat
, your ProgressBar
's color will be colorAccent
you have defined.
Changing colorAccent
will also change your ProgressBar
's color, but these changes also reflects at multiple places. So, if you want a different color just for a specific ProgressBar
you can do that by applying theme to that ProgressBar
alone:
Extend your default theme and override
colorAccent
<style name="AppTheme.WhiteAccent"> <item name="colorAccent">@color/white</item> <!-- Whatever color you want--> </style>
And in
ProgressBar
add theandroid:theme
attribute:android:theme="@style/AppTheme.WhiteAccent"
So it will look something like this:
<ProgressBar
android:id="@+id/loading"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:padding="10dp"
android:theme="@style/AppTheme.WhiteAccent" />
So you are just changing a colorAccent
for your particular ProgressBar
.
Note: Using style
will not work. You need to use android:theme
only.
You can find more use of theme here: https://plus.google.com/u/0/+AndroidDevelopers/posts/JXHKyhsWHAH
Edit
Here is the code for changing the color of ProgressBar by programatically.
ProgressBar progressBar = (ProgressBar) findViewById(R.id.pb_listProgressBar);
int colorCodeDark = Color.parseColor("#F44336");
progressBar.setIndeterminateTintList(ColorStateList.valueOf(colorCodeDark));
回答3:
The easiest way is to use android:indeterminateTint attribute:
<ProgressBar
android:indeterminate="true"
android:indeterminateTint="@android:color/black"
........... />
回答4:
you also can change only the attribute
android:indeterminateDrawable="@drawable/yourxmlfile"
and keep this style
style="@android:style/Widget.ProgressBar.Small"
回答5:
here is how you can do it by java code.
progressBar.getProgressDrawable().setColorFilter(ContextCompat.getColor(getActivity(),R.color.product_status_color), PorterDuff.Mode.MULTIPLY)
回答6:
Here is some explanation. For changing background of a Indeterminate ProgressBar
, you need a rotating ring because it rotates. In the answer of @Chirag, he has defined a rotating ring and applied it to the background of ProgressBar
. If you have a Horizontal ProgressBar
then you need a rectangle
.
PS: I have not tried with other shapes.
回答7:
in xml u can apply color like this
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/loader"
android:indeterminateTint="@color/my_color"
android:layout_centerInParent="true"/>
回答8:
create progress drawable file
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
<shape>
<corners android:radius="5dip" />
<solid android:color="@color/colorWhite" />
</shape>
</item>
<item android:id="@android:id/secondaryProgress">
<clip>
<shape>
<corners android:radius="5dip" />
<solid android:color="@color/colorPrimary" />
</shape>
</clip>
</item>
<item android:id="@android:id/progress">
<clip>
<shape>
<corners
android:radius="5dip" />
<solid android:color="@color/colorPrimary" />
</shape>
</clip>
</item>
and set android:progressDrawable="@drawable/app_progressbar_back"
like this
<ProgressBar
android:id="@+id/dialogProgressView"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:progressDrawable="@drawable/app_progressbar_back"
android:progress="50"
android:layout_marginTop="@dimen/margin_20" />
回答9:
You can also change the color of your progressbar programmatically in your activities oncreate or your fragments onViewCreated()
pBar.getIndeterminateDrawable().setColorFilter(0xFFFF0000, android.graphics.PorterDuff.Mode.MULTIPLY);
Here the color applied is "0xFFFF0000" which is red. You can change it according to your needs

Try using this in your XML
android:indeterminateDrawable="@drawable/yourxmlfile"
style="@android:style/Widget.ProgressBar.Small"
