在android studio中的计算器上切换语句

Question

我正在创建一个转换计算器，其中有12个按钮（是计算器），每个按钮都将我带到另一个活动。在该活动中，我遇到一个有关如何在微调器和键盘按钮上执行switch语句的问题。我已经尽力了，它也正在工作，但是我不知道它是否正确。

switch (v.getId()) {
  case R.id.Button14Keypad1:
    // Table Spoon to Tea Spoon
    if (spinnerFromOne.equals("Table Spoon(tbsp)") && spinnerToOne.equals("Tea Spoon(tsp)")) {
      textview3ToConvert.setText("" + tspOne);
    }

    // Table Spoon to Ounces
    if (spinnerFromOne.equals("Table Spoon(tbsp)") && spinnerToOne.equals("Ounces(oz)")) {
      textview3ToConvert.setText("" + ozOne);
    }

    // Table Spoon to Table Spoon
    if (spinnerFromOne.equals("Table Spoon(tbsp)") && spinnerToOne.equals("Table Spoon(tbsp)")) {
      textview3ToConvert.setText("" + tbsp);
    }

    // Tea Spoon to Tea Spoon
    if (spinnerFromOne.equals("Tea Spoon(tsp)") && spinnerToOne.equals("Tea Spoon(tsp)")) {
      textview3ToConvert.setText("" + tsp);
    }

    // Tea Spoon to Ounces
    if (spinnerFromOne.equals("Tea Spoon(tsp)") && spinnerToOne.equals("Ounces(oz)")) {
      textview3ToConvert.setText("" + ozTwo);
    }

    // Tea Spoon to Table Spoon
    if (spinnerFromOne.equals("Tea Spoon(tsp)") && spinnerToOne.equals("Table Spoon(tbsp)")) {
      textview3ToConvert.setText("" + tbspOne);
    }

    // Ounces to Tea Spoon
    if (spinnerFromOne.equals("Ounces(oz)") && spinnerToOne.equals("Tea Spoon(tsp)")) {
      textview3ToConvert.setText("" + tspTwo);
    }

    // Ounces to Ounces
    if (spinnerFromOne.equals("Ounces(oz)") && spinnerToOne.equals("Ounces(oz)")) {
      textview3ToConvert.setText("" + oz);
    }

    // Ounces to Table Spoon
    if (spinnerFromOne.equals("Ounces(oz)") && spinnerToOne.equals("Table Spoon(tbsp)")) {
      textview3ToConvert.setText("" + tbspTwo);
    }
    break;
}

这是我的相等按钮，所有功能都在其中起作用。
