I have validation for editText
. If the editText
field is empty it should fail validation and stop the user moving on to another Activity
, as a value is required. How to do it? I know this is a basic question, but I can't figure out how to do this.
My code:
btninsert = (Button)findViewById(R.id.btn_insert);
btninsert.setOnClickListener( new View.OnClickListener() {
public void onClick(View v) {
insertValues();
EditText userName = (EditText) findViewById(R.id.editText1);
if( userName.getText().toString().length() == 0 )
userName.setError( "First name is required!" );
Intent i = new Intent(getApplicationContext(), Login.class);
startActivity(i);
}
});
When this Button
is clicked the user is redirect to next screen, but I need that if validation fails they stay on the current Activity
, and only when validation is successful (i.e. a value has been entered) they go to the next Activity
.
It's easy...check if your EditText is empty as in below example below.
if( TextUtils.isEmpty(userName.getText())){
/**
* You can Toast a message here that the Username is Empty
**/
userName.setError( "First name is required!" );
}else{
Intent i = new Intent(getApplicationContext(), Login.class);
startActivity(i);
}
