Whatsapp Message Layout – How to get time-view in the same row

@Hisham Muneer ‘s answer very good.

But there are some problems. For example:

• If the TextView has 2 full lines (end to end), the text will
  intersect with datetime text layout. Finally, the views will
  look like onion effect.
• The text line wraps can’t works efficiently. You must control this
  lines and relocate the datetime view.

I’m going to share my solution, if you will need like this problem.

This is example screenshot

ImFlexboxLayout.java

    public class ImFlexboxLayout extends RelativeLayout {
    private TextView viewPartMain;
    private View viewPartSlave;

    private TypedArray a;

    private RelativeLayout.LayoutParams viewPartMainLayoutParams;
    private int viewPartMainWidth;
    private int viewPartMainHeight;

    private RelativeLayout.LayoutParams viewPartSlaveLayoutParams;
    private int viewPartSlaveWidth;
    private int viewPartSlaveHeight;


    public ImFlexboxLayout(Context context) {
        super(context);
    }

    public ImFlexboxLayout(Context context, AttributeSet attrs) {
        super(context, attrs);

        a = context.obtainStyledAttributes(attrs, R.styleable.ImFlexboxLayout, 0, 0);
    }

    @Override
    protected void onAttachedToWindow() {
        super.onAttachedToWindow();

        try {
            viewPartMain = (TextView) this.findViewById(a.getResourceId(R.styleable.ImFlexboxLayout_viewPartMain, -1));
            viewPartSlave = this.findViewById(a.getResourceId(R.styleable.ImFlexboxLayout_viewPartSlave, -1));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        int heightSize = MeasureSpec.getSize(heightMeasureSpec);

        if (viewPartMain == null || viewPartSlave == null || widthSize <= 0) {
            return;
        }

        int availableWidth = widthSize - getPaddingLeft() - getPaddingRight();
        int availableHeight = heightSize - getPaddingTop() - getPaddingBottom();

        viewPartMainLayoutParams = (LayoutParams) viewPartMain.getLayoutParams();
        viewPartMainWidth = viewPartMain.getMeasuredWidth() + viewPartMainLayoutParams.leftMargin + viewPartMainLayoutParams.rightMargin;
        viewPartMainHeight = viewPartMain.getMeasuredHeight() + viewPartMainLayoutParams.topMargin + viewPartMainLayoutParams.bottomMargin;

        viewPartSlaveLayoutParams = (LayoutParams) viewPartSlave.getLayoutParams();
        viewPartSlaveWidth = viewPartSlave.getMeasuredWidth() + viewPartSlaveLayoutParams.leftMargin + viewPartSlaveLayoutParams.rightMargin;
        viewPartSlaveHeight = viewPartSlave.getMeasuredHeight() + viewPartSlaveLayoutParams.topMargin + viewPartSlaveLayoutParams.bottomMargin;

        int viewPartMainLineCount = viewPartMain.getLineCount();
        float viewPartMainLastLineWitdh = viewPartMainLineCount > 0 ? viewPartMain.getLayout().getLineWidth(viewPartMainLineCount - 1) : 0;

        widthSize = getPaddingLeft() + getPaddingRight();
        heightSize = getPaddingTop() + getPaddingBottom();

        if (viewPartMainLineCount > 1 && !(viewPartMainLastLineWitdh + viewPartSlaveWidth >= viewPartMain.getMeasuredWidth())) {
            widthSize += viewPartMainWidth;
            heightSize += viewPartMainHeight;
        } else if (viewPartMainLineCount > 1 && (viewPartMainLastLineWitdh + viewPartSlaveWidth >= availableWidth)) {
            widthSize += viewPartMainWidth;
            heightSize += viewPartMainHeight + viewPartSlaveHeight;

            widthSize += viewPartMain.getMeasuredWidth();
            heightSize += viewPartMainHeight + viewPartSlaveHeight;
        } else {
            widthSize += viewPartMainWidth + viewPartSlaveWidth;
            heightSize += viewPartMainHeight;
        }

        this.setMeasuredDimension(widthSize, heightSize);
        super.onMeasure(MeasureSpec.makeMeasureSpec(widthSize, MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(heightSize, MeasureSpec.EXACTLY));
    }

    @Override

        super.onLayout(changed, left, top, right, bottom);

        if (viewPartMain == null || viewPartSlave == null) {

        viewPartMain.layout(

You can modify layout xml and some sections related your scenario.

There are 2 important point: you must define in layout xml “viewPartMain”, “viewPartSlave” attributes. Because the code will decide measure via your main(chat textview) and slave(datetime text view) elements.

I wish have good days. Greets.
