Question

to send a message in my application in android i have used the following code.

package wishme.code;


import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class Activity2 extends Activity{

    public void onCreate(Bundle savedInstancestate) {
        super.onCreate(savedInstancestate);
        setContentView(R.layout.main2);
        Button previous=(Button) findViewById(R.id.button_prev);
        Button send=(Button) findViewById(R.id.button_send);
        EditText ph_no=(EditText) findViewById(R.id.edit_phone);
        EditText msg=(EditText) findViewById(R.id.edit_msg);

    }
    public void prevclickhandler(View view)
    {
        switch(view.getId())
        {
        case R.id.button_prev:
        Intent intent=new Intent();
        setResult(RESULT_OK,intent);
        finish();
        break;
        case R.id.button_send:
            **String ph_no= ph_no.getText().tostring();** 
    }}
}

But the line highlighted gives error that is
the method getText is undefined for the type string
how can i resolve this.

Answer 1

Your variables are defined in different scopes. The ph_no EditText is defined in onCreate and not available in your click handler. The ph_no you are actually calling getText() on is the String you are defining.

Instead, you can define the EditText inside your Activity as a instance variable and rename your String so the variable names don’t collide.

Another approach is to just call findViewById when you need access to the EditText, like so:

String ph_no = ((EditText) findViewById(R.id.edit_phone)).getText().toString();
