Force text direction for LeadingMarginSpan2

Question

I am using LeadingSpanMargin2 , as my TextView style suggested, so that it wraps around Image , the problem is that the text I set is dynamic and can be rtl or ltr.

I tried everything I could think of to fix leadingMargin so that it was either right or left in both cases, but to no avail.

I also tried the FlowTextView widget published on github and it does not work very well in rtl cases, so please do not offer this.

Thank you very much.

Here is the code I'm using, which was suggested in another answer:

 public void setFlowText(CharSequence text, int width , int height, TextView messageView) { float textLineHeight = messageView.getPaint().getTextSize(); // Set the span according to the number of lines and width of the image int lines = (int)Math.ceil(height / textLineHeight); //For an html text you can use this line: SpannableStringBuilder ss = (SpannableStringBuilder)Html.fromHtml(text); SpannableString ss = new SpannableString(text); ss.setSpan(new MyLeadingMarginSpan2(lines, width), 0, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); //ss.setSpan(new AlignmentSpan.Standard(Alignment.ALIGN_OPPOSITE), 0, ss.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); messageView.setText(ss); // Align the text with the image by removing the rule that the text is to the right of the image RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)messageView.getLayoutParams(); int[]rules = params.getRules(); rules[RelativeLayout.RIGHT_OF] = 0; } public class MyLeadingMarginSpan2 implements LeadingMarginSpan2 { private int margin; private int lines; private boolean wasDrawCalled = false; private int drawLineCount = 0; public MyLeadingMarginSpan2(int lines, int margin) { this.margin = margin; this.lines = lines; } @Override public int getLeadingMargin(boolean first) { boolean isFirstMargin = first; // a different algorithm for api 21+ if (Build.VERSION.SDK_INT >= 21) { this.drawLineCount = this.wasDrawCalled ? this.drawLineCount + 1 : 0; this.wasDrawCalled = false; isFirstMargin = this.drawLineCount <= this.lines; } return isFirstMargin ? this.margin : 0; } @Override public void drawLeadingMargin(Canvas c, Paint p, int x, int dir, int top, int baseline, int bottom, CharSequence text, int start, int end, boolean first, Layout layout) { this.wasDrawCalled = true; } @Override public int getLeadingMarginLineCount() { return this.lines; } } 

Answer 1

For some unknown reason, you can get the left margin by walking past:

 ss.setSpan(new MyLeadingMarginSpan2(lines, width), 0, 1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 

and to get the correct field you need to go through:

 ss.setSpan(new MyLeadingMarginSpan2(lines, width), 1, 2, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); 

I don’t know what is going on there, but it works!
