Question

嗯，我有一段时间有这个问题了，我觉得它有点讨厌... A使用来自Clans（https://github.com/Clans/FloatingActionButton）的FloatingActionButton并且在触摸FloatingActionMenu之后出于某种原因尝试触摸FloatingActionButton下面的错误显示在我的logcat中。我已经在另一个设备（BQ Aquaris，NEXUS 5和HUAWEI P8）中测试过并且总是得到相同的消息。在FloatingActionButton中第一次触摸后，所有其他触摸均匀，同一个FloatingActionButton开始正常工作，就在第一次我收到此消息...

可能是什么？有人有这个错误吗？

代码：

fab = (FloatingActionButton)findViewById(R.id.capture);
fabCapturar.setOnClickListener(new View.OnClickListener()
{
    @Override
    public void onClick(View v)
    {
         fab.setOnClickListener(new View.OnClickListener()
         {
              @Override
              public void onClick(View v)
              {
                  Intent i = new Intent(MainActivity.this, CameraActivity.class);
                  i.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                        startActivityForResult(i, _Photo);
                        overridePendingTransition(0, 0);
              }
          });
    }

}）;

我对如何解决此错误一无所知......谷歌并不想提供帮助！

感谢您的帮助！

将fab带到所有观点的前面试试这个 fab.bringToFront();

Android：VelocityTracker无法打开＆＃39; / dev / touch＆＃39; （没有权限）
