How to Show Ellipses on My Textview If It Is Greater Than the 1 Line

How can I show ellipses on my TextView if it is greater than the 1 line?

This is a common problem. Try using the following:

android:scrollHorizontally="true"
android:ellipsize="end" 
android:maxLines="1"

.............. the scrollHorizontally is the "special sauce" that makes it work.

How to use custom ellipsis in Android TextView

I've finally managed it in this way (may be not the best one):

private void setLabelAfterEllipsis(TextView textView, int labelId, int maxLines){

    if(textView.getLayout().getEllipsisCount(maxLines-1)==0) {
        return; // Nothing to do
    }

    int start = textView.getLayout().getLineStart(0);
    int end = textView.getLayout().getLineEnd(textView.getLineCount() - 1);
    String displayed = textView.getText().toString().substring(start, end);
    int displayedWidth = getTextWidth(displayed, textView.getTextSize());

    String strLabel = textView.getContext().getResources().getString(labelId);
    String ellipsis = "...";
    String suffix = ellipsis + strLabel;

    int textWidth;
    String newText = displayed;
    textWidth = getTextWidth(newText + suffix, textView.getTextSize());

    while(textWidth>displayedWidth){
        newText = newText.substring(0, newText.length()-1).trim();
        textWidth = getTextWidth(newText + suffix, textView.getTextSize());
    }

    textView.setText(newText + suffix);
}

private int getTextWidth(String text, float textSize){
    Rect bounds = new Rect();
    Paint paint = new Paint();
    paint.setTextSize(textSize);
    paint.getTextBounds(text, 0, text.length(), bounds);

    int width = (int) Math.ceil( bounds.width());
    return width;
}

Ellipsize not show three dots at end of TextView

I used ellipsize=true in the project I developed before, and it worked well in that project, I compared the code of the current project with the previous one. There is no difference between each other, so I am confused with the current project, so I pulled the previous project from github and ran it, and found that it NOT WORK in my xml renderer, but it WORKS on my phone.

Eventually I found it is the problem of the renderer. I found the button to upgrade the renderer. Now I use the latest renderer, and it also works fine in the redener now.

            }
        }
    });

}

private static SpannableStringBuilder addClickablePartTextViewResizable(final Spanned strSpanned, final TextView tv,
                                                                        final int maxLine, final String spanableText, final boolean viewMore) {
    String str = strSpanned.toString();
    SpannableStringBuilder ssb = new SpannableStringBuilder(strSpanned);

    if (str.contains(spanableText)) {

        ssb.setSpan(new MySpannable(false){
            @Override
            public void onClick(View widget) {
                if (viewMore) {
                    tv.setLayoutParams(tv.getLayoutParams());
                    tv.setText(tv.getTag().toString(), TextView.BufferType.SPANNABLE);
                    tv.invalidate();

                    makeTextViewResizable(tv, 3, ".. See More", true);
                }
            }
        }, str.indexOf(spanableText), str.indexOf(spanableText) + spanableText.length(), 0);

    }
    return ssb;

}

Another class:-

import android.graphics.Color;
import android.text.TextPaint;
import android.text.style.ClickableSpan;
import android.view.View;

public class MySpannable extends ClickableSpan {

private boolean isUnderline = true;

/**
 * Constructor
 */
public MySpannable(boolean isUnderline) {
    this.isUnderline = isUnderline;
}

@Override
public void updateDrawState(TextPaint ds) {
    ds.setUnderlineText(isUnderline);
    ds.setColor(Color.parseColor("#1b76d3"));
}

@Override
public void onClick(View widget) {

 }
}

Last step to call it:

DetailTv.setText(discription);
makeTextViewResizable(DetailTv, 3, "See More", true);

How do I tell if my textview has been ellipsized?

You can get the layout of the TextView and check the ellipsis count per line. For an end ellipsis, it is sufficient to check the last line, like this:

Layout l = textview.getLayout();
if (l != null) {
    int lines = l.getLineCount();
    if (lines > 0)
        if (l.getEllipsisCount(lines-1) > 0)
            Log.d(TAG, "Text is ellipsized");
}

This only works after the layout phase, otherwise the returned layout will be null, so call this at an appropriate place in your code.

How to show ellipsis (three dots) at the end of a Text line in Android Jetpack Compose?

Both BasicText and Text have overflow and maxLines arguments which can help you.

Text(myText, maxLines = 1, overflow = TextOverflow.Ellipsis)

Here's a full single-line example:

import androidx.compose.material.Text
import androidx.compose.ui.text.style.TextOverflow

@Composable
fun EllipsisExample() {
    Box(modifier = Modifier.width(160.dp)) {
        Text(
            text = "Lorem ipsum dolor sit amet.",
            maxLines = 1,
            overflow = TextOverflow.Ellipsis
        )
    }
}

Of course you can tune maxLines to fit your needs:

Text(
    text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.",
    maxLines = 2,
    overflow = TextOverflow.Ellipsis
)
