Вот мое решение.
Основная идея состоит в том, чтобы разделить текстовые слова и создать TextView для каждого, оборачивая каждую строку горизонтальным LinearLayout, а строки - вертикальным LinearLayout:
private LinearLayout mDescription; // vertical LinearLayout
private void setDescriptionText(String twitterText){
String[] splitted;
String regexp = "(@[-a-zA-Z0-9_]*)|(#[-a-zA-Z0-9_]*)|(http://[-a-zA-Z0-9/._]*)|(https://[-a-zA-Z0-9/._]*)|( )";
TextSplitter splitter = new TextSplitter(regexp);
splitted = splitter.split(twitterText);
TextView[] textViews = new TextView[splitted.length];
for (int i = 0; i < splitted.length; i++) {
final String str = splitted[i];
TextView textView = new TextView(mDescription.getContext());
textView.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
textViews[i] = textView;
textView.setText(str);
textView.setTypeface(roboReg);
textView.setTextColor(Color.WHITE);
if (str.startsWith("@")){
textView.setTextColor(mLinkColor);
textView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startWebViewActivity("https://twitter.com/"+str.substring(1));
}
});
}else if (str.startsWith("#")){
textView.setTextColor(mLinkColor);
textView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startWebViewActivity("https://twitter.com/#!/search/?q="+str.substring(1) + "&src=hash");
}
});
}else if (str.startsWith("http://") || str.startsWith("https://")){
textView.setTextColor(mLinkColor);
textView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startWebViewActivity(str);
}
});
}
}
int maxWidth = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 210, getResources().getDisplayMetrics());
populateText(mDescription, maxWidth , textViews, mDescription.getContext());
}
private void populateText(LinearLayout ll,int maxWidth, View[] views, Context mContext) {
ll.removeAllViews();
LinearLayout.LayoutParams params;
LinearLayout newLL = new LinearLayout(mContext);
newLL.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
newLL.setGravity(Gravity.LEFT);
newLL.setOrientation(LinearLayout.HORIZONTAL);
int widthSoFar = 0;
for (int i = 0; i < views.length; i++) {
LinearLayout LL = new LinearLayout(mContext);
LL.setOrientation(LinearLayout.HORIZONTAL);
LL.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.BOTTOM);
LL.setLayoutParams(new ListView.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
views[i].measure(0, 0);
params = new LinearLayout.LayoutParams(views[i].getMeasuredWidth(),
LayoutParams.WRAP_CONTENT);
LL.addView(views[i], params);
LL.measure(0, 0);
widthSoFar += views[i].getMeasuredWidth();// YOU MAY NEED TO ADD THE MARGINS
if (widthSoFar >= maxWidth) {
ll.addView(newLL);
newLL = new LinearLayout(mContext);
newLL.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
newLL.setOrientation(LinearLayout.HORIZONTAL);
newLL.setGravity(Gravity.LEFT);
params = new LinearLayout.LayoutParams(LL
.getMeasuredWidth(), LL.getMeasuredHeight());
newLL.addView(LL, params);
widthSoFar = LL.getMeasuredWidth();
} else {
newLL.addView(LL);
}
}
ll.addView(newLL);
}
private class TextSplitter {
private Pattern pattern;
private boolean keep_delimiters;
public TextSplitter(Pattern pattern, boolean keep_delimiters) {
this.pattern = pattern;
this.keep_delimiters = keep_delimiters;
}
public TextSplitter(String pattern, boolean keep_delimiters) {
this(Pattern.compile(pattern == null ? "" : pattern), keep_delimiters);
}
public TextSplitter(String pattern) {
this(pattern, true);
}
public String[] split(String text) {
if (text == null) {
text = "";
}
int last_match = 0;
LinkedList<String> splitted = new LinkedList<String>();
Matcher m = this.pattern.matcher(text);
while (m.find()) {
splitted.add(text.substring(last_match, m.start()));
if (this.keep_delimiters) {
splitted.add(m.group());
}
last_match = m.end();
}
splitted.add(text.substring(last_match));
return splitted.toArray(new String[splitted.size()]);
}
