android textview

Getting height of text view before rendering to layout

Could not find any good solution calculating textview height where text was set before rendering textview to layout. Any help please

2 solutions

Used solution 1 at first and found solution 2 later on. Both work, it’s really what you prefer.

Important is to make sure you got all the dimensions right since mixing font sizes in sp or px will give quite a difference depending on what screen you test on.

A very basic example project is available at

Solution 1 using TextView and MeasureSpec

Main issue with original question is TextView in below method should be configured as our TextView which should be rendered to layout. I think this solution is valuable for many people who faced this problem.

public static int getHeight(Context context, CharSequence text, int textSize, int deviceWidth, Typeface typeface,int padding) {
TextView textView = new TextView(context);
textView.setText(text, TextView.BufferType.SPANNABLE);
textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, textSize);
int widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(deviceWidth, View.MeasureSpec.AT_MOST);
int heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
textView.measure(widthMeasureSpec, heightMeasureSpec);
return textView.getMeasuredHeight();

And an example of how to use this:

// retrieve deviceWidth
int deviceWidth;
WindowManager wm = (WindowManager) textView.getContext().getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
Point size = new Point();
deviceWidth = size.x;
} else {
deviceWidth = display.getWidth();
// the text to check for
String exampleTextToMeasure = "some example text that will be long enough to make this example split over multiple lines so we can't easily predict the final height";
// some dimensions from dimes resources to take into account
int textSize = getContext().getResources().getDimensionPixelSize(R.dimen.text_size);
int padding = getContext().getResources().getDimensionPixelSize(R.dimen.text_padding);
// final calculation of textView height
int measuredTextHeight = getHeight(getContext(), exampleTextToMeasure, textSize, deviceWidth, TypeFace.DEFAULT, padding);

Solution 2 using TextPaint and StaticLayout

This method relies on a TextPaint and StaticLayout which also gives reliable results on all API levels I’ve tested so far. Pay good attention to units of dimensions; all should be in pixels!

Source: Measuring text height to be drawn on Canvas ( Android )

    public static int method1UsingTextPaintAndStaticLayout(
final CharSequence text,
final int textSize, // in pixels
final int deviceWidth, // in pixels
final int padding // in pixels
) {
TextPaint myTextPaint = new TextPaint();
// this is how you would convert sp to pixels based on screen density
//myTextPaint.setTextSize(16 * context.getResources().getDisplayMetrics().density);
Layout.Alignment alignment = Layout.Alignment.ALIGN_NORMAL;
float spacingMultiplier = 1;
float spacingAddition = padding; // optionally apply padding here
boolean includePadding = padding != 0;
StaticLayout myStaticLayout = new StaticLayout(text, myTextPaint, deviceWidth, alignment, spacingMultiplier, spacingAddition, includePadding);
return myStaticLayout.getHeight();
