我想创建自定义视图以显示5种不同的颜色作为附加图像：

有谁知道如何实现上面的视图？

谢谢.

解决方法:

您可以通过将自定义Drawable设置为使用自定义Seekbar来完成此 *** 作.
请参阅this示例.

ProgressItem.java

public class ProgressItem {   public int color;   public float progressItemPercentage;}

CustomSeekbar.java

int progressbarWIDth = getWIDth();int progressbarHeight = getHeight();int thumboffset = getThumbOffset();int lastProgressX = 0;int progressItemWIDth, progressItemRight;for (int i = 0; i < mProgressItemsList.size(); i++) {    ProgressItem progressItem = mProgressItemsList.get(i);    Paint progresspaint = new Paint();    progresspaint.setcolor(getResources().getcolor(progressItem.color));    progressItemWIDth = (int) (progressItem.progressItemPercentage            * progressbarWIDth / 100);    progressItemRight = lastProgressX + progressItemWIDth;    // for last item give right of the progress item to wIDth of the    // progress bar    if (i == mProgressItemsList.size() - 1            && progressItemRight != progressbarWIDth) {        progressItemRight = progressbarWIDth;    }    Rect progressRect = new Rect();    progressRect.set(lastProgressX, thumboffset / 2, progressItemRight,            progressbarHeight - thumboffset / 2);    canvas.drawRect(progressRect, progresspaint);    lastProgressX = progressItemRight;}super.onDraw(canvas);}

activity_main.xml中

<yourpackagename.CustomSeekbar    androID:ID="@+ID/customSeekbar"    androID:layout_wIDth="match_parent"    androID:layout_height="wrap_content"    androID:max="100"    androID:progress="0"    androID:progressDrawable="@androID:color/transparent"    androID:thumb="@drawable/seek_thumb_normal"    androID:thumbOffset="12dp" />

MainActivity.java

private CustomSeekbar seekbar;private float totalSpan = 1500;private float redSpan = 200;private float blueSpan = 300;private float greenSpan = 400;private float yellowSpan = 150;private float darkGreySpan;private ArrayList<ProgressItem> progressItemList;private ProgressItem mProgressItem;@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentVIEw(R.layout.activity_main);seekbar = ((CustomSeekbar) findVIEwByID(R.ID.customSeekbar));initDataToSeekbar();}private voID initDataToSeekbar() {progressItemList = new ArrayList<ProgressItem>();// red spanmProgressItem = new ProgressItem();mProgressItem.progressItemPercentage = ((redSpan / totalSpan) * 100);mProgressItem.color = R.color.red;progressItemList.add(mProgressItem);// blue spanmProgressItem = new ProgressItem();mProgressItem.progressItemPercentage = (blueSpan / totalSpan) * 100;mProgressItem.color = R.color.blue;progressItemList.add(mProgressItem);// green spanmProgressItem = new ProgressItem();mProgressItem.progressItemPercentage = (greenSpan / totalSpan) * 100;mProgressItem.color = R.color.green;progressItemList.add(mProgressItem);// yellow spanmProgressItem = new ProgressItem();mProgressItem.progressItemPercentage = (yellowSpan / totalSpan) * 100;mProgressItem.color = R.color.yellow;progressItemList.add(mProgressItem);// greyspanmProgressItem = new ProgressItem();mProgressItem.progressItemPercentage = (darkGreySpan / totalSpan) * 100;mProgressItem.color = R.color.grey;progressItemList.add(mProgressItem);seekbar.initData(progressItemList);seekbar.invalIDate();}
