尝试将editText的内容从一个复制到另一个时出错

Question

class clicker implements Button.OnClickListener
        {
                public void onClick(View v)
                {                        
                    if(v==button1)
                    {
                        text1.setText(myChoice);
                        Toast.makeText(getBaseContext(), 

                            "~~~~Successfully submitted~~~", 
                            Toast.LENGTH_LONG).show();
                    }

                       if(v==button2)
                    {
                        /*Intent viewDataIntent = new Intent(SurveyActivity.this, Survey2.class);
                        String myData = "You should see this";
                        viewDataIntent.putExtra("valueOne", myData);
                        startActivity(viewDataIntent);
                        */

                           text2.setText(text1.getText());

                           Toast.makeText(getBaseContext(), 

                                   text1.getText(), 
                                Toast.LENGTH_LONG).show();

                    }
                }
        }

在上面的程序中，有两个editText框text1和text2;我试图将text1的内容复制到text2。我试过text2.setText(text1.getText());但是没有用。有什么想法吗？

Answer 1

尝试

text2.setText(text1.getText().toString());

Answer 2

    if(text1.length()!=0){
    text2.setText(text1.getText());
}
