The previous requirement was to use FlipperView to achieve up and down flip effect, but I found that the data was a bit long, which would cause three pieces of data to be put away on a screen. Later, it was changed to a marquee, but the marquee with only text TextView has it, but what should I do if I ask for a small icon behind the text?
(1).：
public class HomeFragment extends BaseFragment {
private MarqueeScroll mMarqueeScroll;
private int[] name_tv = {.name_tv1, .name_tv2, .name_tv3, .name_tv4, .name_tv5, .name_tv6};
private TextView[] name_tvs = new TextView[6];
private int[] name_iv = {.name_iv1, .name_iv2, .name_iv3, .name_iv4, .name_iv5, .name_iv6};
private ImageView[] name_ivs = new ImageView[6];
private ArrayList<HomeFlipperBean> mFlipperList = new ArrayList<HomeFlipperBean>();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = (.fragment_homenews, null);
mMarqueeScroll = (MarqueeScroll) ();
for (int i = 0; i < name_tv.length; i++) {
name_tvs[i] = (TextView) (name_tv[i]);
name_ivs[i] = (ImageView) (name_iv[i]);
}
();
// Analysis here ResponseBaseBean<ArrayList<HomeFlipperBean>> responsBaseBean = (mFlipperData,
new TypeReference<ResponseBaseBean<ArrayList<HomeFlipperBean>>>() {
});
mFlipperList = ();
if (mFlipperList != null && () > 0) {
// ForegroundColorSpan is the foreground color of text, BackgroundColorSpan is the background color of text ForegroundColorSpan span1 = new ForegroundColorSpan(0xFF535353);
ForegroundColorSpan span2 = new ForegroundColorSpan(0xFF346699);
for (int i = 0; i < name_tvs.length; i++) {
HomeFlipperBean bean = (i);
name_tvs[i].setText(() + " " + ());
if ("up".equals(())) {
name_ivs[i].setBackgroundResource(.in_img3);
} else {
name_ivs[i].setBackgroundResource(.in_img4);
}
int length = ().length();
SpannableStringBuilder builder = new SpannableStringBuilder(name_tvs[i].getText().toString());
(span1, 0, length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
(span2, length + 1, name_tvs[i].getText().toString().length(),
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
name_tvs[i].setText(builder);
}
}
}
}

(3).: Customize HorizontalScrollView
public class MarqueeScroll extends HorizontalScrollView implements Runnable {
private View inner;
private Bitmap bitmap = null;
/**
* Scroll step length
*/
private int step = 1;
private int x;
private int width;
private int pWidth;
private int pHeight;
public MarqueeScroll(Context context, AttributeSet attrs) {
super(context, attrs);
setBackgroundColor(0xFFE1F4FF);
}
@Override
protected void onFinishInflate() {
if (getChildCount() == 1) {
inner = getChildAt(0);
}
}
@Override
protected void onDetachedFromWindow() {
();
(this);
}
@Override
protected void onDraw(Canvas canvas) {
if (getWidth() == 0) {
lp = getLayoutParams();
= pWidth;
= pHeight;
setLayoutParams(lp);
}
if (bitmap == null && inner != null) {
width = ();
bitmap = (width, (), Config.RGB_565);
Canvas canvas1 = new Canvas(bitmap);
(canvas1);
pWidth = getWidth();
pHeight = getHeight();
if (inner != null) {
removeViewInLayout(inner);
inner = null;
}
run();
}
if (bitmap != null) {
int nowX = x;
nowX -= step;
(bitmap, nowX, 0, null);
if (nowX < 0) {
(bitmap, width + nowX /* + space */, 0, null);
}
if (nowX <= -width) {
nowX = 0;
}
x = nowX;
}
(canvas);
}
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
(msg);
}
};
@Override
public void run() {
invalidate();
(this, 1);
}
}
