Question

I’m wondering if it is possible to clear data from a customized dialog. I have a customized dialog having 5 textview and edittexts. I have two buttons named “Send ” and “Clear” first is supposed to send the data to database and second is meant to clear the data, in case if user wants to re-enter the whole text there in the 5 edittext fields.

Any idea how to do this?

SIMPLE:

You want to set the text of the editText to an empty string or “”.

IN DEPTH:

You need to import:

import android.widget.EditText;

Make sure you have this below your onCreate:

EditText field1 = (EditText) findViewById(R.id.editText1);
EditText field2 = (EditText) findViewById(R.id.editText2);
EditText field3 = (EditText) findViewById(R.id.editText3);
EditText field4 = (EditText) findViewById(R.id.editText4);

Onclick you want to:

field1 .setText("");
field2 .setText("");
field3 .setText("");
field4 .setText("");

OVERKILL:

Here is how I would do it:

//START OF CUSTOM ALERTDIALOG//

    void openCustomDialog(){
         AlertDialog.Builder customDialog 
          = new AlertDialog.Builder(ACTIVITYNAMEHERE.this);
         customDialog.setTitle("TITLE HERE");
         customDialog.setIcon(R.drawable.ic_action);

//OPTIONAL Enter custom layout here if you want
//LayoutInflater layoutInflater 
//=
//(LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE)//;
//View view=layoutInflater.inflate(R.layout.mylayout,null);

      customDialog.setPositiveButton("Send", new DialogInterface.OnClickListener(){

       public void onClick(DialogInterface arg0, int arg1) {
        // TODO Auto-generated method stub
               //CODE FOR DATABASE
           YOURACTIVITYHERE.this.finish();
       }});

      customDialog.setNegativeButton("Reset Fields", new DialogInterface.OnClickListener(){

       public void onClick(DialogInterface arg0, int arg1) {
        // TODO Auto-generated method stub

       }});
     //CODE I PROVIDED up top
            field1 .setText("");
            field2 .setText("");
            field3 .setText("");
            field4 .setText("");
            customDialog.setView(view);
            customDialog.show();
        }




    //END OF CUSTOM ALERTDIALOG//
