Android自定义View之比赛时间闪动效果

效果

代码

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;
}

}

使用注意事项

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();
}

谢谢
