具體實作代碼
LikesView
public class LikesView extends TextView {
private Context mContext;
private List list;
public LikesView(Context context) {
this(context, null);
}
public LikesView(Context context, @Nullable AttributeSet attrs) {
this(context, attrs, 0);
}
public LikesView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
mContext = context;
}
public void setList(List list) {
this.list = list;
}
public void notifyDataSetChanged() {
if (list == null || list.size() <= 0) {
return;
}
SpannableStringBuilder builder = new SpannableStringBuilder();
builder.append(setImageSpan());
for (int i = 0; i < list.size(); i++) {
UserBean item = list.get(i);
builder.append(setClickableSpan(item.getUserName(), item));
if (i != list.size() - 1) {
builder.append(" , ");
} else {
builder.append(" ");
}
}
setText(builder);
setMovementMethod(new CircleMovementMethod(0xffcccccc, 0xffcccccc));
// setMovementMethod(LinkMovementMethod.getInstance());
}
public SpannableString setClickableSpan(final String item, final UserBean bean) {
final SpannableString string = new SpannableString(item);
ClickableSpan span = new ClickableSpan() {
@Override
public void onClick(View widget) {
// TODO: 2017/9/3 評論使用者名字點選事件
Toast.makeText(mContext, bean.getUserName(), Toast.LENGTH_SHORT).show();
}
@Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
// 設定顯示的文字顔色
ds.setColor(0xff387dcc);
ds.setUnderlineText(false);
}
};
string.setSpan(span, 0, string.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
return string;
}
private SpannableString setImageSpan() {
String text = " ";
SpannableString imgSpanText = new SpannableString(text);
imgSpanText.setSpan(new ImageSpan(getContext(), R.mipmap.img_like_icon, DynamicDrawableSpan.ALIGN_BASELINE),
0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
return imgSpanText;
}
}
附: CircleMovementMethod , UserBean 代碼請到 Android 朋友圈之評論回複清單中擷取，這裡不重複添加。
用法
android:id="@+id/likeView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/dp_10"
android:textSize="@dimen/sp_18" />
likeView = LvV.find(this, R.id.likeView);
likeView.setList(Data.getLikes());
likeView.notifyDataSetChanged();
代碼已整理到Github
