Android TextView实现词组高亮的示例代码

protected void onDraw(Canvas canvas) {    super.onDraw(canvas);    float x_draw = getPaddingLeft();    float y_draw = getPaddingTop() + dfPaint.getTextSize();    for (ExtendText t : extendTexts) {      Paint paint = t.isHighlight ? hlPaint : dfPaint;      float textLen = paint.measureText(t.textUnit);      if (x_draw + textLen > width) {        x_draw = getPaddingLeft();        y_draw += paint.getTextSize();      }      canvas.drawText(t.textUnit, x_draw, y_draw, paint);      x_draw += textLen;    }  }

public class MainActivity extends Activity {  private final static String TEXT = "";  private final static String[] HIGHLIGHT = {};  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    HighLightTextView hlTv = (HighLightTextView) findViewById(R.id.hlTv);    hlTv.setDisplayedText(TEXT, Arrays.asList(HIGHLIGHT));    hlTv.setDefaultColor(Color.BLACK);    hlTv.setHighlightColor(ContextCompat.getColor(this, R.color.colorPrimary));  }}
