How to navigate to another screen according to the text in editText?

Question

I want my app to be such that when the editText1 has value (2) without brackets in it, the button press (with onClick="k") would navigate to MainActivity2. And if the text is (3), the activity MainActivity3 would open. I guess it'll use If function. How can I just implement this in my app? Sorry for silly questions, I'm just a newbie. ;-;

Answer 1

Within onClickListener, get the data from edittext as string and compare it using switch-case :

String string = editText1.getText().toString();
switch(string){

case "2":
//Start MainActivity2
break;

case "3":
//Start MainActivity3
break;
}

Answer 2

I'm not sure why exactly you're doing this, but here's what you can do:

1. Set the EditText property to accept only digits/numbers

2. onClick() of the button, access the number entered in EditText by

   editText1.getText().toString()

3. After you've done that, use switch-case statements to launch the desired activity.

Answer 3

Try this:-

String string = editText1.getText().toString();

       if(string.equals("2"))
       {
        Intent i = new  Intent(getApplicationContext(),MainActivity2.class);
        startActivity(i); 
       }
       else if(equals("3"))
       {
        Intent i = new   Intent(getApplicationContext(),MainActivity3.class); 
        startActivity(i);
       }

Answer 4

Remove the methods inside the switch-case

    case "2": 
    public void kden(View v) { 
         // TODO Auto-generated method stub 
         Intent i = new Intent(getApplicationContext(),MainActivity2.class);
         startActivity(i); 
    } 
    break; 

and try this

 case "2":    
    Intent i = new Intent(getApplicationContext(),MainActivity2.class);
    startActivity(i); 
    break;

First, retrieve the value from the EditText. If you only want digits/numbers then you can set this in the properties for theEditText. For now, we'll leave it as accepting string values. Assuming the identifier for your EditText is 'editText1':

String targetActivity = editText1.getText().toString();

Secondly, you need to use conditional statements to evaluate which Activity to launch. @Sree used switch-case in his answer, here I will use if statements as they are much easier to read and understand.

Intent i;

if(targetActivity.equals("k")){
   i = new Intent(YourCurrentActivity.this, StartSomeActivity.class);
   startActivity(i);
}

else if(targetActivity.equals("3")){
    i = new Intent(YourCurrentActivity.this, StartAnotherActivity.class);
    startActivity(i);
}

Obviously you can change what values to compare against, I used k and 3 as those were the examples you gave in your question. Also be sure to swap out 'YourCurrentActivity' for the current Activity name and 'StartSomeActivity' and 'StartAnotherActivity' with the names of the desires activites you want to launch.

Answer 6

At least post the code properly in comment...

• Before using switch case with String read Why can't I switch on a String?

And with value you can use this on your button click event

int key = Integer.parseInt(edit.getText().toString());
Intent i;
switch (key) {
  case 1:
      i = new Intent(MainActivity.this,MainActivity2.class); 
    break;
  case 2:
      i = new Intent(MainActivity.this,MainActivity3.class); 
    break;
}
startActivity(i);
