是否可以在 Android 的 ImageButton 和 Button 小部件中使用相同的代码？

Question

我正在开发一个安卓应用程序。

我的要求是使用由两个不同控件运行的相同代码，一个是 imageButton，第二个是 Button。

为此，我使用的是这种方法。

 public void onClick_Office_Mgmt(View v)
    {
        Intent i=new Intent(Admin_Dashboard.this,Office_Mgmt.class);        
        i.putExtra("USERNAME", unm);        
        startActivity(i);   
    }

我用这个方法来Buttons OnClick 事件。

<Button
            android:id="@+id/btn_office_mgt"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="?android:selectableItemBackground"
            android:onClick="onClick_Office_Mgmt"
            android:text="Office Mgt"
            android:textColor="#ff0000"/>

但是当我尝试在 imageButtons OnClick 事件中调用相同的方法时，它会导致错误。

<ImageButton
            android:id="@+id/ibtn_office_mgt"
            android:layout_width="108dp"
            android:layout_height="108dp"
            android:background="?android:selectableItemBackground"
            android:onClick="onClick_Office_Mgmt"
            android:scaleType="fitXY"
            android:src="@drawable/office_icon" />

谁能告诉它为什么会发生？以及如何解决这个问题？

Answer 1

我认为当您使用模拟器进行测试时会出现此问题。更简单的解决方法是在

下的模拟设备中禁用 “Exchange Services”

设置 -> 应用程序 -> 全部

第二种解决方案是，您可以删除当前的模拟器并创建相同的模拟器。有时这可以解决问题。

编辑

如果模拟器中的主机 GPU 已启用，只需将其禁用并重试。

您遇到的问题与模拟器有关。如果您有设备，请尝试在那里检查一次。这将节省您的时间。

Answer 2

当然有可能。

我认为由于小部件的声明，您有一个错误。

你可以通过方法使用它。

问题是您必须删除按钮和图像按钮的声明。
