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

android:progressTint="#ffffff"

对于我的不确定的进度条(转轮),我只是设置了一个颜色过滤器的可绘制。工作很好,只是一行。

将颜色设置为红色的示例:

ProgressBar spinner = new android.widget.ProgressBar(
                context,
                null,
                android.R.attr.progressBarStyle);

spinner.getIndeterminateDrawable().setColorFilter(0xFFFF0000, android.graphics.PorterDuff.Mode.MULTIPLY);

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

更改进度条的前景和背景颜色的最简单的方法是

<ProgressBar
                        style="@android:style/Widget.ProgressBar.Horizontal"
                        android:id="@+id/pb_main"
                        android:layout_width="match_parent"
                        android:layout_height="8dp"
                        android:progress="30"
                        android:progressTint="#82e9de"
                        android:progressBackgroundTint="#82e9de"
                        />

只需添加

                        android:progressTint="#82e9de" //for foreground colour
                        android:progressBackgroundTint="#82e9de" //for background colour

这不是程序化的,但我认为它可以帮助很多人。 我尝试了很多,最有效的方法是在。xml文件中添加这行到我的ProgressBar:

            android:indeterminate="true"
            android:indeterminateTintMode="src_atop"
            android:indeterminateTint="@color/secondary"

所以在最后这段代码为我做了:

<ProgressBar
            android:id="@+id/progressBar"
            style="?android:attr/progressBarStyleLarge"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:layout_marginTop="50dp"
            android:layout_marginBottom="50dp"
            android:visibility="visible"
            android:indeterminate="true"
            android:indeterminateTintMode="src_atop"
            android:indeterminateTint="@color/secondary">

该解决方案适用于API 21+

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
