I'm developing an application and I needed to display a Toast at some point inside a Thread, but I'm not getting it, does anyone know how it's possible and if it's possible to do so? Thank you in advance.
Note: if it is not a toast, it could be a Dialog too, but it has the same problem.
The reason is that it is not allowed to access objects that use the UI, such as Toast , a Thread other than UIThread MainThread) .
In the% method of the Thread method, use the run() method to put a Runnable in UIThread .
new Thread() {
public void run() {
....
....
runOnUiThread(new Runnable() {
@Override
public void run() {
//Coloque aqui o código que necessita de correr
//na UI thread, como por exemplo o Toast
}
});
}
}.start();
Note: The same applies if you have an AsyncTask and if you want to use Toast in runOnUiThread() .
I think you need to call Toast.makeTexts from the Thread UI, inside your thread you can do this:
activity.runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(activity, "Sou um toast dentro de uma thread", Toast.LENGTH_SHORT).show();
}
});
