Android - Change the text of the positive button of an AlertDialog
I reuse an AlertDialog box in my android app.
I create a dialog in the onCreateDialog() method and in the onPrepareDialog() method, I try to change the text of the positiveButton using the following code.
alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, this.getString(R.string.add), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//Handler code
}
}
The onclick listener is开发者_如何学运维 getting changed, but the button text is not changed.
Is it a bug in Android or am I doing something wrong?
One solution is just to force the button to redraw. For example, a button to cancel a lengthy operation might change to 'OK' on complete, e.g.
Button button = progressDialog.getButton(ProgressDialog.BUTTON1); button.setText("OK"); button.invalidate();
This works for me
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_ID:
return AlertDialog.Builder(this).setTitle(R.string.contact_groups_add)
.setView(addView).setPositiveButton(R.string.ok,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
}
}).setNegativeButton(R.string.cancel,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int whichButton) {
}
}).create();
}
return null;
}
