Android 如何调整文本字体大小以适合 textview

How to adjust text font size to fit textview

提问by rudas

Is there any way in android to adjust the textsize in a textview to fit the space it occupies?

在android中有什么方法可以调整textview中的textsize以适应它占用的空间吗？

E.g. I'm using a TableLayoutand adding several TextViews to each row. Since I don't want the TextViews to wrap the text I rather see that it lowers the font size of the content.

例如，我正在使用 a并向每一行TableLayout添加几个TextViews。由于我不希望TextViews 包裹文本，我宁愿看到它降低了内容的字体大小。

Any ideas?

有任何想法吗？

I have tried measureText, but since I don't know the size of the column it seems troublesome to use. This is the code where I want to change the font size to something that fits

我试过measureText，但由于我不知道列的大小，所以使用起来似乎很麻烦。这是我想将字体大小更改为适合的代码

TableRow row = new TableRow(this);   
for (int i=0; i < ColumnNames.length; i++) {    
    TextView textColumn = new TextView(this);      
    textColumn.setText(ColumnNames[i]);
    textColumn.setPadding(0, 0, 1, 0);
    textColumn.setTextColor(getResources().getColor(R.drawable.text_default));          
    row.addView(textColumn, new TableRow.LayoutParams()); 
} 
table.addView(row, new TableLayout.LayoutParams());

The solution below incorporates all of the suggestions here. It starts with what was originally posted by Dunni. It uses a binary search like gjpc's, but it is a bit more readable. It also include's gregm's bug fixes and a bug-fix of my own.

下面的解决方案包含了此处的所有建议。它从最初由 Dunni 发布的内容开始。它使用类似于 gjpc 的二分搜索，但可读性更强。它还包括 gregm 的错误修复和我自己的错误修复。

I've written a class that extends TextView and does this. It just uses measureText as you suggest. Basically it has a maximum text size and minimum text size (which can be changed) and it just runs through the sizes between them in decrements of 1 until it finds the biggest one that will fit. Not particularly elegant, but I don't know of any other way.

我编写了一个扩展 TextView 的类并执行此操作。它只是按照您的建议使用 measureText 。基本上它具有最大文本大小和最小文本大小（可以更改），并且它只是以 1 的递减量遍历它们之间的大小，直到找到适合的最大文本大小。不是特别优雅，但我不知道任何其他方式。

Here is the code:

这是代码：

public class FontFitTextView extends TextView {

    public FontFitTextView(Context context) {

        initialise();
    }

    public FontFitTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialise();
    }

    private void initialise() {
        testPaint = new Paint();
        testPaint.set(this.getPaint());
        //max size defaults to the intially specified text size unless it is too small
        maxTextSize = this.getTextSize();
        if (maxTextSize < 11) {
            maxTextSize = 20;
        }
        minTextSize = 10;
    }

    /* Re size the font so the specified text fits in the text box
     * assuming the text box is the specified width.
     */
    private void refitText(String text, int textWidth) { 
        if (textWidth > 0) {
            int availableWidth = textWidth - this.getPaddingLeft() - this.getPaddingRight();
            float trySize = maxTextSize;

            testPaint.setTextSize(trySize);
            while ((trySize > minTextSize) && (testPaint.measureText(text) > availableWidth)) {
                trySize -= 1;
                if (trySize <= minTextSize) {
                    trySize = minTextSize;
                    break;
                }
                testPaint.setTextSize(trySize);
            }

            this.setTextSize(trySize);
        }
    }

    @Override
    protected void onTextChanged(final CharSequence text, final int start, final int before, final int after) {
        refitText(text.toString(), this.getWidth());
    }

    @Override
    protected void onSizeChanged (int w, int h, int oldw, int oldh) {
        if (w != oldw) {
            refitText(this.getText().toString(), w);
        }
    }

    //Getters and Setters
    public float getMinTextSize() {
        return minTextSize;
    }

    public void setMinTextSize(int minTextSize) {
        this.minTextSize = minTextSize;
    }

    public float getMaxTextSize() {
        return maxTextSize;
    }

    public void setMaxTextSize(int minTextSize) {
        this.maxTextSize = minTextSize;
    }

    //Attributes
    private Paint testPaint;
    private float minTextSize;
    private float maxTextSize;

}

This is speedplane's FontFitTextView, but it only decreasesfont size if needed to make the text fit, and keeps its font size otherwise. It does not increase the font size to fit height.

这是speedplane 的FontFitTextView，但它只会在需要使文本适合时减小字体大小，否则保持其字体大小。它不会增加字体大小以适应高度。

public class FontFitTextView extends TextView {

    // Attributes
    private Paint mTestPaint;
    private float defaultTextSize;

    public FontFitTextView(Context context) {
        super(context);

    public FontFitTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialize();
    }

    private void initialize() {
        mTestPaint = new Paint();
        mTestPaint.set(this.getPaint());
        defaultTextSize = getTextSize();
    }

    /* Re size the font so the specified text fits in the text box
     * assuming the text box is the specified width.
     */
    private void refitText(String text, int textWidth) {

        if (textWidth <= 0 || text.isEmpty())
            return;

        int targetWidth = textWidth - this.getPaddingLeft() - this.getPaddingRight();

        // this is most likely a non-relevant call
        if( targetWidth<=2 )
            return;

        // text already fits with the xml-defined font size?
        mTestPaint.set(this.getPaint());
        mTestPaint.setTextSize(defaultTextSize);
        if(mTestPaint.measureText(text) <= targetWidth) {
            this.setTextSize(TypedValue.COMPLEX_UNIT_PX, defaultTextSize);
            return;
        }

        // adjust text size using binary search for efficiency
        float hi = defaultTextSize;
        float lo = 2;
        final float threshold = 0.5f; // How close we have to be
        while (hi - lo > threshold) {
            float size = (hi + lo) / 2;
            mTestPaint.setTextSize(size);
            if(mTestPaint.measureText(text) >= targetWidth ) 
                hi = size; // too big
            else 
                lo = size; // too small

        }

        // Use lo so that we undershoot rather than overshoot
        this.setTextSize(TypedValue.COMPLEX_UNIT_PX, lo);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
        int height = getMeasuredHeight();
        refitText(this.getText().toString(), parentWidth);
        this.setMeasuredDimension(parentWidth, height);
    }

    @Override
    protected void onTextChanged(final CharSequence text, final int start,
            final int before, final int after) {
        refitText(text.toString(), this.getWidth());
    }

    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        if (w != oldw || h != oldh) {
            refitText(this.getText().toString(), w);
        }
    }

}

Here is an example how it could be used in xml:

这是一个如何在 xml 中使用它的示例：

<com.your.package.activity.widget.FontFitTextView
    android:id="@+id/my_id"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:text="My Text"
    android:textSize="60sp" />

This would keep the font size to 60sp as long as the text fits in width. If the text is longer, it will decrease font size. In this case, the TextViews height will also change because of height=wrap_content.

只要文本适合宽度，这将使字体大小保持为 60sp。如果文本较长，则会减小字体大小。在这种情况下，TextViews 的高度也会因为 发生变化height=wrap_content。

Here is my solution which works on emulator and phones but not very well on Eclipse layout editor. It's inspired from kilaka's code but the size of the text is not obtained from the Paint but from measuring the TextView itself calling measure(0, 0).

这是我的解决方案，它适用于模拟器和手机，但不适用于 Eclipse 布局编辑器。它的灵感来自 kilaka 的代码，但文本的大小不是从 Paint 获得的，而是通过测量 TextView 本身调用measure(0, 0).

To use the new maxFontSizeattribute, don't forget to add xmlns:res-auto="http://schemas.android.com/apk/res-auto"as show in the example.

要使用新maxFontSize属性，请不要忘记添加xmlns:res-auto="http://schemas.android.com/apk/res-auto"示例中的显示。

I had the same problem and wrote a class that seems to work for me. Basically, I used a static layout to draw the text in a separate canvas and remeasure until I find a font size that fits. You can see the class posted in the topic below. I hope it helps.

我遇到了同样的问题，写了一个似乎对我有用的类。基本上，我使用静态布局在单独的画布中绘制文本并重新测量，直到找到适合的字体大小。您可以在下面的主题中看到该课程。我希望它有帮助。

You can now do this without a third party library or a widget. It's built into TextView in API level 26. Add android:autoSizeTextType="uniform"to your TextViewand set height to it. That's all.

您现在可以在没有第三方库或小部件的情况下执行此操作。它内置于 API 级别 26 中的 TextView。添加android:autoSizeTextType="uniform"到您的TextView并为其设置高度。就这样。

You can also use TextViewCompatfor compatibility.

您也可以TextViewCompat用于兼容性。

I found the following to work nicely for me. It doesn't loop and accounts for both height and width. Note that it is important to specify the PX unit when calling setTextSize on the view. Thanks to the tip in a previous post for this!

我发现以下对我来说很好用。它不循环并考虑高度和宽度。请注意，在视图上调用 setTextSize 时指定 PX 单位很重要。感谢上一篇文章中的提示！

Paint paint = adjustTextSize(getPaint(), numChars, maxWidth, maxHeight);
setTextSize(TypedValue.COMPLEX_UNIT_PX,paint.getTextSize());

Here is the routine I use, passing in the getPaint() from the view. A 10 character string with a 'wide' character is used to estimate the width independent from the actual string.

这是我使用的例程，从视图中传入 getPaint()。带有“宽”字符的 10 个字符的字符串用于估计与实际字符串无关的宽度。

private static final String text10="OOOOOOOOOO";
public static Paint adjustTextSize(Paint paint, int numCharacters, int widthPixels, int heightPixels) {
    float width = paint.measureText(text10)*numCharacters/text10.length();
    float newSize = (int)((widthPixels/width)*paint.getTextSize());
    paint.setTextSize(newSize);

    // remeasure with font size near our desired result
    width = paint.measureText(text10)*numCharacters/text10.length();
    newSize = (int)((widthPixels/width)*paint.getTextSize());
    paint.setTextSize(newSize);

    // Check height constraints
    FontMetricsInt metrics = paint.getFontMetricsInt();
    float textHeight = metrics.descent-metrics.ascent;
    if (textHeight > heightPixels) {
        newSize = (int)(newSize * (heightPixels/textHeight));
        paint.setTextSize(newSize);
    }

    return paint;
}

Slight modification to onMeasure:

对 onMeasure 稍作修改：

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
    int parentHeight = MeasureSpec.getSize(heightMeasureSpec);
    refitText(this.getText().toString(), parentWidth);
    this.setMeasuredDimension(parentWidth, parentHeight);
}

And binary search on refitText:

对 refitText 进行二分搜索：

private void refitText(String text, int textWidth) 
{ 
    if (textWidth > 0) 
    {
        int availableWidth = textWidth - this.getPaddingLeft() - this.getPaddingRight();         
        int trySize = (int)maxTextSize;
        int increment = ~( trySize - (int)minTextSize ) / 2;

        testPaint.setTextSize(trySize);
        while ((trySize > minTextSize) && (testPaint.measureText(text) > availableWidth)) 
        {
            trySize += increment;
            increment = ( increment == 0 ) ? -1 : ~increment / 2;
            if (trySize <= minTextSize) 
            {
                trySize = (int)minTextSize;
                break;
            }
            testPaint.setTextSize(trySize);
        }

        this.setTextSize( TypedValue.COMPLEX_UNIT_PX, trySize);
    }
}

Works with modification

与修改一起工作

You need to set the text view size like this because otherwise setTextSize assumes the value is in SP units:

您需要像这样设置文本视图大小，否则 setTextSize 假定该值以 SP 为单位：

setTextSize(TypedValue.COMPLEX_UNIT_PX, trySize);

And you needed to explicitly add this code.

并且您需要显式添加此代码。

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
    int parentHeight = MeasureSpec.getSize(heightMeasureSpec);
    refitText(this.getText().toString(), parentWidth);
}
