ProgressBar bar;

private Handler progressBarHandler = new Handler();

GradientDrawable progressGradientDrawable = new GradientDrawable(
        GradientDrawable.Orientation.LEFT_RIGHT, new int[]{
                0xff1e90ff,0xff006ab6,0xff367ba8});
ClipDrawable progressClipDrawable = new ClipDrawable(
        progressGradientDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
Drawable[] progressDrawables = {
        new ColorDrawable(0xffffffff),
        progressClipDrawable, progressClipDrawable};
LayerDrawable progressLayerDrawable = new LayerDrawable(progressDrawables);


int status = 0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // TODO Auto-generated method stub
    setContentView(R.layout.startup);

    bar = (ProgressBar) findViewById(R.id.start_page_progressBar);
    bar.setProgress(0);
    bar.setMax(100);

    progressLayerDrawable.setId(0, android.R.id.background);
    progressLayerDrawable.setId(1, android.R.id.secondaryProgress);
    progressLayerDrawable.setId(2, android.R.id.progress);

    bar.setProgressDrawable(progressLayerDrawable);
}

这帮助我通过代码设置自定义颜色为progressbar。希望能有所帮助

在Xml中添加ProgressBar

适用于SDK 21及以上版本

android:indeterminateTint="@color/red"

默认值(不确定)

add

android:indeterminateTint="@color/white"

为确定

    android:progressTint="@color/color_1"

    //OR
    progressBar.getProgressDrawable().setColorFilter( PorterDuffColorFilter(Color.RED,android.graphics.PorterDuff.Mode.SRC_IN));

android:progressTint="#ffffff" 

对于水平的ProgressBar，你也可以使用ColorFilter，就像这样:

progressBar.getProgressDrawable().setColorFilter(
    Color.RED, android.graphics.PorterDuff.Mode.SRC_IN);

注意:这将修改应用程序中所有进度条的外观。要只修改一个特定的进度条，请执行以下操作:

Drawable progressDrawable = progressBar.getProgressDrawable().mutate();
progressDrawable.setColorFilter(Color.RED, android.graphics.PorterDuff.Mode.SRC_IN);
progressBar.setProgressDrawable(progressDrawable);

如果progressBar是不确定的，则使用getIndeterminateDrawable()而不是getProgressDrawable()。

因为棒棒糖(API 21)，你可以设置一个进度色调:

progressBar.setProgressTintList(ColorStateList.valueOf(Color.RED));

这招对我很管用:

<ProgressBar
 android:indeterminateTint="#d60909"
 ... />
