Android自定义View实现比赛时间闪动效果

本文实例为大家分享了Android实现比赛时间闪动效果的具体代码,供大家参考,具体内容如下

效果

代码

上代码

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

我的RecyclerView框架是BRVAH

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();

}

}

}

使用的时候一定要判断是否正在运行

if (!twinkleTextView.isRun()) {

twinkleTextView.beginRun();

}

谢谢。
