在使用Androidx的databing时，在项目中添加以下ViewBindingAdapter.java 代码，即可解决用户快速点击的问题

public class ViewBindingAdapter {

@BindingAdapter({"android:onClick","android:clickable"})

public static void setOnClick(View view, View.OnClickListener clickListener,

boolean clickable) {

setOnClick(view, clickListener);

view.setClickable(clickable);

}

@BindingAdapter({"android:onClick"})

public static void setOnClick(View view,final View.OnClickListener clickListener) {

final long[] mHits =new long[2];

view.setOnClickListener(new View.OnClickListener() {

@Override

            public void onClick(View v) {

System.arraycopy(mHits,1,mHits,0,mHits.length -1);

mHits[mHits.length -1] = SystemClock.uptimeMillis();

if (mHits[0] < (SystemClock.uptimeMillis() -500)) {

clickListener.onClick(v);

}else {

Log.i(Cons.TAG,"误触");

}

}

});

}

}
