推荐答案
好，您必须首先从 android:foreground =?android:attr/selectableItemBackground" 删除空间并将其添加到所有按钮
Well You have to First Remove space from this android:foreground="?android:attr/selectableItemBackground" and add this to all the button
android:clickable ="false"
如果要使用 Button 打开活动，则必须将 setOnClickListener 放到Button中.否则，如果要使用 Cardview 打开活动，您必须将 setOnClickListener 放入cardview.
If you want to Open Activity With Button Then you have to put setOnClickListener to Button .Else if you want to open Activity with Cardview you have to put setOnClickListener to cardview.
将此方法用于 OnClick 方法:
@Override
public void onClick(View view) {
if (view==LoginBtn){
startActivity(new Intent(this,Login1.class));
}else if(view==Capture){
startActivity(new Intent(this,Capture.class));
}
//Do rest by yourself.
}
