In your EditText you add the addTextChangedListener()
method as follows:
package genesysgeneration.svg;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.widget.EditText;
public class Main2Activity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
EditText editText = (EditText)findViewById(R.id.editText);
editText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
//aqui você executa uma determinada ação antes da modificação do editText
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
//aqui você executa uma determinada ação durante a modificação do editText
}
@Override
public void afterTextChanged(Editable s) {
//aqui você executa uma determinada ação depois da modificação do editText
}
});
}
}
In it you have 3 options for executing an action, before edtText is modified, during and after. You choose one of the three according to your need.
