Question

我有四个使用4个不同阵列的ArrayAdapters

console.log(JSON.stringify(myJson))

我有两个微调器

        persistentVolumeClaim:
          claimName: camera-pv
      restartPolicy: Always

在单击的按钮上，adapter1 = new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_spinner_item,getResources().getStringArray( R.array.array1) ); adapter2 = new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_spinner_item,getResources().getStringArray(R.array. array2)); adapter3 = new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_spinner_item,getResources().getStringArray(R.array. array3)); adapter4 = new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_spinner_item,getResources().getStringArray(R.array. array4));和spinnerFrom = findViewById(R.id.unit_From_spinner) spinnertTo = findViewById(R.id.unit_To_spinner);填充代码中指定的适配器。

我的主要想法是在项目中编写如下内容：

spinnerFrom

问题：如何获取当前使用的适配器并通过spinnertTo和{指定其名称（if (spinnerFrom use adapter 1 or adapter 2 || spinnerTo use adapter 1 or adapter 2){ some code } else if (spinnerFrom use adapter 3 or adapter 4 || spinnerTO use adapter 3 or adapter 4){ some code } / adapter1 / adapter2 / adapter3） {1}}旋转器并使if-else（或者我应该使用adapter4）结构吗？

谢谢！

一个简单的相等检查应该起作用：

if (spinner.getAdapter() == adapterInstance) //etc

通常，您不想在Java中执行此操作，因为它比较实例而不是值，但是在这种情况下，它应该做您需要的操作，即比较实例。

检查当前使用哪个ArrayAdapter Spinner
