因为我一直在寻找这个，而我刚刚找到了一个解决方案，但这里没有，我将把它写在这里，以供将来参考。

注意:这段代码是直接从谷歌Android棒棒糖拨号器一段时间后，我不记得如果改变在当时。此外，我不知道这是在哪个许可证下，但我有理由认为它是Apache 2.0。

类ResizeTextView，实际的视图

public class ResizeTextView extends TextView {

private final int mOriginalTextSize;
private final int mMinTextSize;
private final static int sMinSize = 20;
public ResizeTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    mOriginalTextSize = (int) getTextSize();
    mMinTextSize = (int) sMinSize;
}
@Override
protected void onTextChanged(CharSequence text, int start, int lengthBefore, int lengthAfter) {
    super.onTextChanged(text, start, lengthBefore, lengthAfter);
    ViewUtil.resizeText(this, mOriginalTextSize, mMinTextSize);
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
    super.onSizeChanged(w, h, oldw, oldh);
    ViewUtil.resizeText(this, mOriginalTextSize, mMinTextSize);
}

这个ResizeTextView类可以扩展TextView和它所有的孩子，我的理解，所以EditText以及。

ViewUtil类带有resizeText方法(…)

import android.graphics.Paint;
import android.util.TypedValue;
import android.widget.TextView;

public class ViewUtil {

    private ViewUtil() {}

    public static void resizeText(TextView textView, int originalTextSize, int minTextSize) {
        final Paint paint = textView.getPaint();
        final int width = textView.getWidth();
        if (width == 0) return;
        textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, originalTextSize);
        float ratio = width / paint.measureText(textView.getText().toString());
        if (ratio <= 1.0f) {
            textView.setTextSize(TypedValue.COMPLEX_UNIT_PX,
                    Math.max(minTextSize, originalTextSize * ratio));
        }
    }
}

您应该将您的视图设置为

<yourpackage.yourapp.ResizeTextView
            android:layout_width="match_parent"
            android:layout_height="64dp"
            android:gravity="center"
            android:maxLines="1"/>

希望能有所帮助!

这里还有另一个解决方案，只是为了好玩。它可能不是很有效，但它确实处理了文本的高度和宽度，以及有标记的文本。

@Override
protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec)
{
    if ((MeasureSpec.getMode(widthMeasureSpec) != MeasureSpec.UNSPECIFIED)
            && (MeasureSpec.getMode(heightMeasureSpec) != MeasureSpec.UNSPECIFIED)) {

        final float desiredWidth = MeasureSpec.getSize(widthMeasureSpec);
        final float desiredHeight = MeasureSpec.getSize(heightMeasureSpec);

        float textSize = getTextSize();
        float lastScale = Float.NEGATIVE_INFINITY;
        while (textSize > MINIMUM_AUTO_TEXT_SIZE_PX) {
            // Measure how big the textview would like to be with the current text size.
            super.onMeasure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);

            // Calculate how much we'd need to scale it to fit the desired size, and
            // apply that scaling to the text size as an estimate of what we need.
            final float widthScale = desiredWidth / getMeasuredWidth();
            final float heightScale = desiredHeight / getMeasuredHeight();
            final float scale = Math.min(widthScale, heightScale);

            // If we don't need to shrink the text, or we don't seem to be converging, we're done.
            if ((scale >= 1f) || (scale <= lastScale)) {
                break;
            }

            // Shrink the text size and keep trying.
            textSize = Math.max((float) Math.floor(scale * textSize), MINIMUM_AUTO_TEXT_SIZE_PX);
            setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);
            lastScale = scale;
        }
    }
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

我发现下面的方法对我很有用。它不循环，同时考虑高度和宽度。注意，在视图上调用setTextSize时指定PX单位是很重要的。

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

下面是我使用的例程，从视图中传入getPaint()。带有'wide'字符的10个字符的字符串用于估计独立于实际字符串的宽度。

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;
}

你可以使用android.text.StaticLayout类。这就是TextView内部使用的。

感谢Chase和onoelle，对于懒惰的程序员，让我在这里发布一个他们神奇的合并代码的工作版本，在一个按钮上改编，而不是一个TextView。

用AutoResizeTextButtons替换所有的按钮(不是ImageButtons)，同样无聊的问题也得到了解决。

这是代码。我只是删除了导入。

用法:

把一个AutoResizeTextButton在你的xml中代替一个正常的按钮，没有改变 一切。 在onCreate()中放置(例如):

    myButton = (AutoResizeTextButton)getView().findViewById(id.myButton);
    myButton.setMinTextSize(8f);
    myButton.resizeText();

更新:下面的代码也满足了一个理想的AutoScaleTextView的要求，如这里所述:自动适合Android的TextView，并被标记为赢家。

更新2:增加了对maxlines的支持，现在在API级别16之前工作正常。

更新3:支持android: drawablleft, android:drawableRight, android:drawableTop和android:drawableBottom标签添加，感谢MartinH在这里的简单修复。

我的要求有点不同。我需要一种有效的方法来调整大小，因为我是动画一个整数从，可能是0 ~4000在TextView在2秒内，我想相应地调整大小。我的解决方法有点不同。这是最终的结果:

以及产生它的代码:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="16dp" >

    <com.vj.widgets.AutoResizeTextView
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:ellipsize="none"
        android:maxLines="2"
        android:text="Auto Resized Text, max 2 lines"
        android:textSize="100sp" /> <!-- maximum size -->

    <com.vj.widgets.AutoResizeTextView
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:ellipsize="none"
        android:gravity="center"
        android:maxLines="1"
        android:text="Auto Resized Text, max 1 line"
        android:textSize="100sp" /> <!-- maximum size -->

    <com.vj.widgets.AutoResizeTextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
