Question

I wrote android code to send data that taken from textbox from one activity to appear in Toast message in another activity in the same project

and this is code

the code of main activity is

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button btn = (Button) findViewById(R.id.button1);
    EditText txt = (EditText) findViewById(R.id.editText1);

    btn.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            String str = txt.getText().toString();
            Intent i = new Intent(MainActivity.this,Target.class);
            i.putExtra("Name", str);
            startActivity(i);
        }
    });

}

and the code of target activity is

public void onCreat(Bundle savedInstanceState )
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_target);

    Bundle b = getIntent().getExtras();
    String s = b.getString("Name");
    Toast.makeText(Target.this, s, Toast.LENGTH_SHORT).show();
}

when I run the project and write something in textbox and press the button
the other activity is opened and nothing happened.

can you help me and tell me why this problem occurred?

Answer 1

I got the problem, small typo

public void onCreat(Bundle savedInstanceState)

should be

public void onCreate(Bundle savedInstanceState)

missing e 🙂

It will not override the super class onCreate, though it is a valid function. But never be called.
