本文将带你了解Android应用开发之Android 自定义设置文本字体间间距，希望本文对大家学Android有所帮助。

自定义spacingTextView 继承TextView，代码如下:
    public class SpacingTextView extends TextView {
    private float letterSpacing = LetterSpacing.BIGGEST;
    private CharSequence originalText = “”;
      ?12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364<code>public   SpacingTextView(Context context)   {    super(context);} public SpacingTextView(Context   context, AttributeSet attrs){    super(context,   attrs);    originalText =   super.getText();    applyLetterSpacing();    this.invalidate();} public   SpacingTextView(Context context, AttributeSet attrs, int   defStyle){    super(context, attrs,   defStyle);} public float getLetterSpacing()   {    return letterSpacing;} public void   setLetterSpacing(float letterSpacing)   {    this.letterSpacing =   letterSpacing;    applyLetterSpacing();} @Overridepublic   void setText(CharSequence text, BufferType type)   {    originalText =   text;    applyLetterSpacing();} @Overridepublic   CharSequence getText() {    return originalText;} /** *   字距为任何字符串（技术上，一个简单的方法为CharSequence不使用）的TextView */private void   applyLetterSpacing() {    if (this == null ||   this.originalText == null) return;    StringBuilder   builder = new StringBuilder();    for(int i = 0; i <   originalText.length(); i++)   {        String c = ""+   originalText.charAt(i);        builder.append(c.toLowerCase());        if(i+1   < originalText.length())   {            builder.append("\u00A0");        }    }    SpannableString   finalText = new   SpannableString(builder.toString());    if(builder.toString().length()   > 1) {        for(int i = 1; i   < builder.toString().length(); i+=2) {            finalText.setSpan(new   ScaleXSpan((letterSpacing+1)/10), i, i+1,   Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);        }    }    super.setText(finalText,   BufferType.SPANNABLE);} public class LetterSpacing   {    public final static float NORMAL =   0;    public final static float NORMALBIG =   (float)0.025;    public final static float BIG = (float)0.05;    public   final static float BIGGEST = (float)0.2;}</code>
    }
    代码中调用：
    public class SpacingTextViewActivity extends BaseActivity {
    <code><code>private SpacingTextView   spacingTextView; @Overrideprotected void onCreate(Bundle   savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_spacing_text_view);    spacingTextView=findView(R.id.space_text);    spacingTextView.setText(getResources().getString(R.string.space_test));    spacingTextView.setLetterSpacing(ConvertUtils.dip2px(this,20)); }</code></code>
    }
