Java Android Studio:ImageButton';轻触时未激活
我正在开发这个应用程序,目前正在测试它,我不太确定出了什么问题。当我点击或按住甲板按钮时,绝对不会发生任何事情。logcat中唯一显示的是触摸事件。我认为我的格式可能有问题,但由于这是我第一次使用Java(过去只在微处理器类中使用汇编),我不确定它可能是什么 编辑:删除了许多与问题无关的额外代码 下面是MainActivity.javaJava Android Studio:ImageButton';轻触时未激活,java,android,android-studio,Java,Android,Android Studio,我正在开发这个应用程序,目前正在测试它,我不太确定出了什么问题。当我点击或按住甲板按钮时,绝对不会发生任何事情。logcat中唯一显示的是触摸事件。我认为我的格式可能有问题,但由于这是我第一次使用Java(过去只在微处理器类中使用汇编),我不确定它可能是什么 编辑:删除了许多与问题无关的额外代码 下面是MainActivity.java public class MainActivity extends AppCompatActivity { int i=0; int VOA=

如果您使用了
longclickListener()
建议阅读:感谢这一帮助,这样我就可以知道按钮实际上在工作,我将不得不对我的代码进行更多的测试,以找出它到底出了什么问题。现在谢谢你。
Deck.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
List c= new ArrayList();
Collections.shuffle(c);
return true; // change to true
}});
