I tried to use enter in EditText
as an action, but i always get force closed. Please tell me know where is the wrong code from my program.
Here is my code.
noteField = (EditText)findViewById(R.id.noteNote);
noteField.setOnKeyListener(new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)){
builder.setTitle("Saved")
.setMessage("Confirm saved notes?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
onSaved();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
})
.setNeutralButton("Not yet", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
}).setCancelable(true).show();
return true;
}
return false;
}
});
Logcat.
