我在我的Android应用程序中使用水平进度条,我想改变它的进度颜色(默认为黄色)。我如何使用代码(而不是XML)做到这一点?


当前回答

简单的使用方法:

DrawableCompat.setTint(progressBar.getIndeterminateDrawable(),yourColor)

其他回答

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

使用android.support.v4.graphics.drawable.DrawableCompat:

            Drawable progressDrawable = progressBar.getIndeterminateDrawable();
            if (progressDrawable  != null) {
                Drawable mutateDrawable = progressDrawable.mutate();
                DrawableCompat.setTint(mutateDrawable, primaryColor);
                progressBar.setProgressDrawable(mutateDrawable);
            }

简单的使用方法:

DrawableCompat.setTint(progressBar.getIndeterminateDrawable(),yourColor)

更改水平进度条颜色(kotlin):

fun tintHorizontalProgress(progress: ProgressBar, @ColorInt color: Int = ContextCompat.getColor(progress.context, R.color.colorPrimary)){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        progress.progressTintList = ColorStateList.valueOf(color)
    } else{
        val layerDrawable = progress.progressDrawable as? LayerDrawable
        val progressDrawable = layerDrawable?.findDrawableByLayerId(android.R.id.progress)
        progressDrawable?.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
    }
}

更改不确定的ProgressBar颜色:

fun tintIndeterminateProgress(progress: ProgressBar, @ColorInt color: Int = ContextCompat.getColor(progress.context, R.color.colorPrimary)){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        progress.indeterminateTintList = ColorStateList.valueOf(color)
    } else {
        (progress.indeterminateDrawable as? LayerDrawable)?.apply {
            if (numberOfLayers >= 2) {
                setId(0, android.R.id.progress)
                setId(1, android.R.id.secondaryProgress)
                val progressDrawable = findDrawableByLayerId(android.R.id.progress).mutate()
                progressDrawable.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
            }
        }
    }
}

它最终正常地着色pre-lollipop progressBars

这个答案中可能有一件事没有提到:

如果您的主题是从theme继承的。AppCompat, ProgressBar将假定你在主题中定义为“colorAccent”的颜色。

所以,使用. .

< name = " colorAccent > @color /项目custom_color < - >项目

..将自动将ProgressBar的颜色着色为@color/custom_color。
