Question

我想在我的应用程序中设置进度条颜色为默认进度条颜色为浅白色，而我的应用程序也具有白色背景，因此无法正确显示。所以请给我解决方案。感谢。

Answer 1

@Chirag：我不认为这样就够了吗？您的代码可能会在背景处设置渐变，但白色微调器仍将在此处。

我为自定义微调器工作所做的是设置一个带有背景可绘制（图像或形状）的ProgressBar。 ProgressBar动画在这里用Java调用。

<ProgressBar
     android:id="@+id/ProgressBar01" 
     android:layout_width="40px"
     android:layout_height="40px"
     style="?android:attr/progressBarStyle"
     android:indeterminateOnly="false"
     android:background ="@drawable/spinner_blue_76"
     />

<强> splash_spinner.xml

<?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="359"
    android:duration="1000"
    android:repeatMode="restart"
    android:repeatCount="infinite"
    android:interpolator="@android:anim/linear_interpolator">
</rotate>

<强> LauncherActivity

    ...
    ProgressBar t = (ProgressBar) findViewById(R.id.ProgressBar01);
    t.startAnimation(AnimationUtils.loadAnimation(this,R.anim.splash_spinner));
    ...

spinner_blue_76 （或其他）

它可能不是正确的方式，但它运作良好。（我的灰色背景上现在有一个蓝色的微调器）

请创建一个xml文件名progress.xml并将其放在res / xml文件夹中，并在该xml文件中写下以下代码。

<?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>

创建此xml文件后，将progressbars背景设置为此xml ..

像

<ProgressBar
  android:id="@+id/ProgressBar01" 
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background = "@xml/progress">

不是正确的答案，但我仍然做的是这样的：要获得黑色ProgressBar，请使用其中一种反向样式：

<ProgressBar style="@android:style/Widget.ProgressBar.Inverse"/>
<ProgressBar style="@android:style/Widget.ProgressBar.Large.Inverse"/>
<ProgressBar style="@android:style/Widget.ProgressBar.Small.Inverse"/>

为此，您需要至少拥有Android SDK等级4（Android 1.6）。

对于横向样式ProgressBar，我使用：

    import android.widget.ProgressBar;
    import android.graphics.drawable.GradientDrawable;
    import android.graphics.drawable.ClipDrawable;
    import android.view.Gravity;
    import android.graphics.drawable.Drawable;
    import android.graphics.drawable.LayerDrawable;

    public void setColours(ProgressBar progressBar,
                            int bgCol1, int bgCol2, 
                            int fg1Col1, int fg1Col2, int value1,
                            int fg2Col1, int fg2Col2, int value2)
      {
        //If solid colours are required for an element, then set
        //that elements Col1 param s the same as its Col2 param
        //(eg fg1Col1 == fg1Col2).

        //fgGradDirection and/or bgGradDirection could be parameters
        //if you require other gradient directions eg LEFT_RIGHT.

        GradientDrawable.Orientation fgGradDirection
            = GradientDrawable.Orientation.TOP_BOTTOM;
        GradientDrawable.Orientation bgGradDirection
            = GradientDrawable.Orientation.TOP_BOTTOM;

        //Background
        GradientDrawable bgGradDrawable = new GradientDrawable(
                bgGradDirection, new int[]{bgCol1, bgCol2});
        bgGradDrawable.setShape(GradientDrawable.RECTANGLE);
        bgGradDrawable.setCornerRadius(5);
        ClipDrawable bgclip = new ClipDrawable(
                bgGradDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);     
        bgclip.setLevel(10000);

        //SecondaryProgress
        GradientDrawable fg2GradDrawable = new GradientDrawable(
                fgGradDirection, new int[]{fg2Col1, fg2Col2});
        fg2GradDrawable.setShape(GradientDrawable.RECTANGLE);
        fg2GradDrawable.setCornerRadius(5);
        ClipDrawable fg2clip = new ClipDrawable(
                fg2GradDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);        

        //Progress
        GradientDrawable fg1GradDrawable = new GradientDrawable(
                fgGradDirection, new int[]{fg1Col1, fg1Col2});
        fg1GradDrawable.setShape(GradientDrawable.RECTANGLE);
        fg1GradDrawable.setCornerRadius(5);
        ClipDrawable fg1clip = new ClipDrawable(
                fg1GradDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);        

        //Setup LayerDrawable and assign to progressBar
        Drawable[] progressDrawables = {bgclip, fg2clip, fg1clip};
        LayerDrawable progressLayerDrawable = new LayerDrawable(progressDrawables);     
        progressLayerDrawable.setId(0, android.R.id.background);
        progressLayerDrawable.setId(1, android.R.id.secondaryProgress);
        progressLayerDrawable.setId(2, android.R.id.progress);

        //Copy the existing ProgressDrawable bounds to the new one.
        Rect bounds = progressBar.getProgressDrawable().getBounds();
        progressBar.setProgressDrawable(progressLayerDrawable);     
        progressBar.getProgressDrawable().setBounds(bounds);

        // setProgress() ignores a change to the same value, so:
        if (value1 == 0)
            progressBar.setProgress(1);
        else
            progressBar.setProgress(0);
        progressBar.setProgress(value1);

        // setSecondaryProgress() ignores a change to the same value, so:
        if (value2 == 0)
            progressBar.setSecondaryProgress(1);
        else
            progressBar.setSecondaryProgress(0);
        progressBar.setSecondaryProgress(value2);

        //now force a redraw
        progressBar.invalidate();
      }

示例调用将是：

      setColours(myProgressBar, 
              0xff303030,   //bgCol1  grey 
              0xff909090,   //bgCol2  lighter grey 
              0xff0000FF,   //fg1Col1 blue 
              0xffFFFFFF,   //fg1Col2 white
              50,           //value1
              0xffFF0000,   //fg2Col1 red 
              0xffFFFFFF,   //fg2Col2 white
              75);          //value2

如果您不需要“辅助进度”，只需将value2设置为value1。
