EditText getText but not showing

Question

I have a edit text and button

EditText edit=(EditText) findViewById(R.id.edittext);
Button btn=(Button) findViewById(R.id.btn);

btn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v){
Toast.makeText(context,edit.getText().toString(),Toast.LENGTH_SHORT).show();
edit.setText("hello");
}
}

but when i click the button i can get the toast with "hello"(the text of the edittext) but the edittext is empty. is it a bug?

(edit) this is my full code finding = (EditText) rowView.findViewById(R.id.txtfindings); finding.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new AlertDialog.Builder(context)
.setTitle("Findings")
.setMultiChoiceItems(
CustomDialog.service.getFindingsArray(), // array of string ex(cd,hard drive,motherboard)
_selectionsFindings, // boolean array size=size of findingsarray
new DialogSelectionClickHandler()) // set click handler on checkbox
.setPositiveButton("OK",
new DialogButtonClickHandler() //set button click
).create()
.show();
}
});

public class DialogSelectionClickHandler implements
DialogInterface.OnMultiChoiceClickListener {
public void onClick(DialogInterface dialog, int clicked,boolean selected) {
} }

public class DialogButtonClickHandler implements
        DialogInterface.OnClickListener {
    public void onClick(DialogInterface dialog, int clicked) {
        switch (clicked) {
        case DialogInterface.BUTTON_POSITIVE:
            printSelectedFinding();//call the function
            break;
        }
    }
}

protected void printSelectedFinding() {
    String textfinding = "";
    ArrayList<String> values = new ArrayList<String>(Arrays.asList(finding
            .getText().toString().split(","))); 
    if (!finding.getText().toString().equalsIgnoreCase("")) {
        if (!finding.getText().toString().substring(finding.getText().toString().length() - 1,
        finding.getText().toString().length()).equalsIgnoreCase(",")) {
            textfinding = ",";   //check if last character is == ,
        }
    }
    for (int i = 0; i < CustomDialog.service.getFindingsArray().length; i++) {
        if (_selectionsFindings[i]  //check which item is checked
                && !values.contains(CustomDialog.service.getFindingsArray()[i].trim())) { // check if edittext contains the text
            textfinding += CustomDialog.service.getFindingsArray()[i] + ","; // concatinate string
        }
    }
     finding.append(textfinding); // this where error happens finding is an edittext ex(textfinding = hard drive) finding should have "hard drive"
                    // but it is not displayed but when i use       getText() i can get "hard drive"
}

the issue could be because of sudden change of the text to HELLO, toast usually gets visible after a while so in the mean time it gets the changed value of HELLO and shows that, you need to make some kind of stay between two — Saqib, Jan 17 '14 at 06:10
the issue is in the edittext.i can get the text of edittext but the word "hello" is not showing even i edit.setText("hello"); — the bosxcz, Jan 17 '14 at 06:14

it is different because i am able to use getText() and having an output of "hello" but in my widget "hello" is not present — the bosxcz, Jan 17 '14 at 06:23
Your code shouldn't work unless you have set edit as final. I feel there might be some other overlooked issue(duplicate variable?) — hypd09, Jan 17 '14 at 06:25
i double checked it already no final no double variable. i dont get what i am doing wrong. it is so confusing because i can use getText but the text is not visible -.- — the bosxcz, Jan 17 '14 at 06:28
you have to setText before you show the toast, then it wont be blank — Navaneeth, Jan 17 '14 at 06:30
it is the same if i click the button several times after the first click the edittext should contain "hello" but it is not happening — the bosxcz, Jan 17 '14 at 06:31

You are setting text in editText by

 edit.setText("hello");

Try it with removing it.

So your code should :

EditText edit=(EditText) findViewById(R.id.edittext);
Button btn=(Button) findViewById(R.id.btn);

btn.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v){
Toast.makeText(context,edit.getText().toString(),Toast.LENGTH_SHORT).show();
//edit.setText("hello"); <====== comment this line and check
}
}

toast is working problem is edittext even i setText("hello"); it is still blank – the bosxcz Jan 17 '14 at 06:17
actually it is dynamic.i put it in a listview – the bosxcz Jan 17 '14 at 06:21
give us your full code, including the adapter if you are using this inside one. Possible that recycling views is making it appear blank. – hypd09 Jan 17 '14 at 06:27
