Android自定义View实现比赛时间闪动效果

public class TwinkleTextView extends TextView implements Runnable {  /**   * 是否显示   */  private boolean flag = true;  /**   * 闪动内容   */  private String twinkleText = "'";  /**   * 闪动时间   */  private int delayMillis = 500;  private boolean run = false;  public TwinkleTextView(Context context, AttributeSet attrs) {    super(context, attrs);  }  public TwinkleTextView(Context context, AttributeSet attrs, int defStyleAttr) {    super(context, attrs, defStyleAttr);  }  @TargetApi(Build.VERSION_CODES.LOLLIPOP)  public TwinkleTextView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {    super(context, attrs, defStyleAttr, defStyleRes);  }  public void beginRun(){    run = true;    run();  }  @Override  public void run() {    if (flag){      setVisibility(VISIBLE);      flag = false;    }else{      setVisibility(INVISIBLE);      flag = true;    }    postDelayed(this, delayMillis);  }  public String getTwinkleText() {    return twinkleText;  }  public void setTwinkleText(String twinkleText) {    this.twinkleText = twinkleText;    setText(twinkleText);  }  public int getDelayMillis() {    return delayMillis;  }  public void setDelayMillis(int delayMillis) {    this.delayMillis = delayMillis;  }  public boolean isRun() {    return run;  }  public void setRun(boolean run) {    this.run = run;  }}

public class MyAdapter extends BaseQuickAdapter<User, BaseViewHolder> {  public MyAdapter(int layoutResId, @Nullable List<User> data) {    super(layoutResId, data);  }  @Override  protected void convert(BaseViewHolder helper, User item) {    TextView textView = helper.getView(R.id.text);    textView.setText(helper.getAdapterPosition() + "");    TwinkleTextView twinkleTextView = helper.getView(R.id.twinkle);    twinkleTextView.setDelayMillis(500);    if (!twinkleTextView.isRun()) {      twinkleTextView.beginRun();    }  }}

if (!twinkleTextView.isRun()) {  twinkleTextView.beginRun();}
