下面直接是关于解决该问题的代码（根据别人的代码进行了修正以及测试，保证可以修改字体尺寸、颜色、根据padding调整，如果需要支持其他的格式可以将对应的属性添加至Paint类型的对象中）：

1 public class NsTextView extends TextView { 2     private String text; 3     private float textSize; 4     private float paddingLeft; 5     private float paddingRight; 6     private int textColor; 7     private Paint paint1 = new Paint(); 8     private float textShowWidth; 9 10     public NsTextView(Context context, AttributeSet attrs) {11         super(context, attrs);12         text = this.getText().toString();13         textSize = this.getTextSize();14         textColor = this.getTextColors().getDefaultColor();15         paddingLeft = this.getPaddingLeft();16         paddingRight = this.getPaddingRight();17         paint1.setTextSize(textSize);18         paint1.setColor(textColor);19         paint1.setAntiAlias(true);20     }21 22     @Override23     protected void onDraw(Canvas canvas) {24         textShowWidth = this.getMeasuredWidth() - paddingLeft - paddingRight;25         int lineCount = 0;26         text = this.getText().toString();27         if (text == null)28             return;29         char[] textCharArray = text.toCharArray();30         float drawedWidth = 0;31         float charWidth;32         for (int i = 0; i < textCharArray.length; i++) {33             charWidth = paint1.measureText(textCharArray, i, 1);34             if (textCharArray[i] == '\n') {35                 lineCount++;36                 drawedWidth = 0;37                 continue;38             }39             if (textShowWidth - drawedWidth < charWidth) {40                 lineCount++;41                 drawedWidth = 0;42             }43             canvas.drawText(textCharArray, i, 1, paddingLeft + drawedWidth,44                     (lineCount + 1) * textSize, paint1);45             drawedWidth += charWidth;46         }47         setHeight((int) ((lineCount + 1) * (int) textSize ));48     }49 }
