显示消息的 Toast 方法

Question

I created a method for toast the problem is in some cases I want to display a toast message with an integer and sometimes I want to display toast message without the integer. I know this could be made possible by creating two separate functions but is it possible with one method itself.

public void maketoast(String string, Integer inte){
    Toast.makeText(this, string+inte, Toast.LENGTH_SHORT).show();
}

The following are the cases of the method call :

maketoast("Greater than ",2);

maketoast("Greater ",null);

Output: In first call, I need the output as "Greater than 2" In the second call I need the output as "Greater" but currently I am getting "Greater null"

Answer 1

Java has a ternary operator . Using it will help to abbreviate your code:

public void maketoast(String string, Integer inte){
    Toast.makeText(this, inte != null ? string+inte : string, Toast.LENGTH_SHORT).show();
}

Answer 2

Adding null to a string converts null to "null". I recommend this

public void maketoast(String string, Integer inte){
    if(inte == null) 
      Toast.makeText(this, string, Toast.LENGTH_SHORT).show();
    else
      Toast.makeText(this, string+inte, Toast.LENGTH_SHORT).show();
}
