直接上代码

自定义TextView

文字展示

public class StrokeTextView extends TextView {

 private TextView borderText = null;///用于描边的TextView
 private Context mContext;

 public StrokeTextView(Context context) {
  super(context);
  mContext = context;
  borderText = new TextView(context);
  init();
 }

 public StrokeTextView(Context context, AttributeSet attrs) {
  super(context, attrs);
  mContext = context;
  borderText = new TextView(context, attrs);
  init();
 }

 public StrokeTextView(Context context, AttributeSet attrs, int defStyle) {
  super(context, attrs, defStyle);
  mContext = context;
  borderText = new TextView(context, attrs, defStyle);
  init();
 }

 public void init() {
  TextPaint tp1 = borderText.getPaint();
  tp1.setStrokeWidth(12);         //设置描边宽度
  tp1.setStyle(Paint.Style.STROKE);        //对文字只描边
  //设置自定义字体
  Typeface fromAsset = Typeface.createFromAsset(mContext.getAssets(), "fonts/Alibaba-PuHuiTi-Heavy.ttf");
  borderText.setTypeface(fromAsset, Typeface.ITALIC); //自定义字体 ITALIC斜体
  borderText.setTextColor(Color.parseColor("#F46059")); //设置描边颜色
  borderText.setShadowLayer(3.0F, 2F, 2F, Color.parseColor("#ffd44042")); //设置阴影效果（投影）
  borderText.setGravity(getGravity());
 }

 @Override
 public void setLayoutParams(ViewGroup.LayoutParams params) {
  super.setLayoutParams(params);
  borderText.setLayoutParams(params);
 }

 @Override
 protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
  CharSequence tt = borderText.getText();

  //两个TextView上的文字必须一致
  if (tt == null || !tt.equals(this.getText())) {
   borderText.setText(getText());
   this.postInvalidate();
  }
  super.onMeasure(widthMeasureSpec, heightMeasureSpec);
  borderText.measure(widthMeasureSpec, heightMeasureSpec);
 }

 protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
  super.onLayout(changed, left, top, right, bottom);
  borderText.layout(left, top, right, bottom);
 }

 @Override
 protected void onDraw(Canvas canvas) {
  borderText.draw(canvas);
  super.onDraw(canvas);
 }

}
