Question

I’m trying to create a tablayout where have two tabs for now. One tab has a button,editText and another has a ediText. When I press the button I need to read the text from the another tab and put it in current edittext. But when I try this, I’ve been getting a force close error.For testing I tried putting the content of the editText to the button name.

package android.work;

            import android.app.Activity;
            import android.content.res.Resources;
            import android.os.Bundle;
            import android.view.View;
            import android.widget.Button;
            import android.widget.EditText;
            import android.widget.TabHost;
            import android.widget.TextView;

            public class tabcontent1 extends Activity
            {
                public void onCreate(Bundle savedInstanceState)
                {       
                    super.onCreate(savedInstanceState);
                    //TextView txt=new TextView(this);
                    //txt.setText("Tab1");
                    setContentView(R.layout.tab1content);

                    final Button but=(Button)findViewById(R.id.button1);
                    but.setOnClickListener(new View.OnClickListener() 
                    {

                        public void onClick(View v) 
                        {
                            EditText ed=(EditText)findViewById(R.id.editText2);
                            String str=ed.getText().toString();
                            EditText ed1=(EditText)findViewById(R.id.editText1);
                            but.setText(str);
                        }
                    });
                }
            }

Check if you’re not getting nullpointerexception…
