checkbox-Checkboxes 讓 toast 多次出現的問題

Checkboxes 讓 toast 多次出現的問題

我在程序中設置了兩個 checkboxes 和兩個 EditText。點擊一個 CheckBox 時 EditText 消失，然後顯示Toast ，"Your Information is Saved"，如何再次點擊 CheckBox時，另一個Toast 會顯示"Enter Your Email Address"。兩個toast在每次點擊後都可以正常運行。這是什麼原因？

on.setOnClickListener(new View.OnClickListener() {
  public void onClick(View v) {
    if (((CheckBox) v).isChecked())
      receiverEmail.setVisibility(View.GONE);
    if (((CheckBox) v).isChecked())
      Toast.makeText(getApplicationContext(), 
      "Your Information is Saved", Toast.LENGTH_LONG).show();
    else
      receiverEmail.setVisibility(View.VISIBLE);
      Toast.makeText(getApplicationContext(), 
      "Enter Your Email Address", Toast.LENGTH_LONG).show();
  }
});

on2.setOnClickListener(new View.OnClickListener() {
  public void onClick(View v) {
    if (((CheckBox) v).isChecked())
      clientID.setVisibility(View.GONE);
    if (((CheckBox) v).isChecked())
      Toast.makeText(getApplicationContext(), 
      "Your Information is Saved", Toast.LENGTH_LONG).show();
    else
      clientID.setVisibility(View.VISIBLE);
      Toast.makeText(getApplicationContext(), 
      "Enter Your Email Address", Toast.LENGTH_LONG).show();
  }
});

最佳回答：

if (((CheckBox) v).isChecked()){
      Toast.makeText(getApplicationContext(), 
      "Your Information is Saved", Toast.LENGTH_LONG).show();
}
    else{
      receiverEmail.setVisibility(View.VISIBLE);
      Toast.makeText(getApplicationContext(), 
      "Enter Your Email Address", Toast.LENGTH_LONG).show();
}

if else 如果省略｛｝的話只會執行臨近的一行代碼，第二行是不會執行的，你的問題應該是因為else後執行一行代碼receiverEmail.setVisibility(View.VISIBLE);，導致Toast.makeText(getApplicationContext(),
"Enter Your Email Address", Toast.LENGTH_LONG).show();無論如何都會執行的
樓主看下是不是因為這個。。。
