renderizado - problemas con android studio

Intente invocar el método virtual ''int android.text.Layout.getLineCount()'' en una referencia de objeto nula

Question

Recibo aleatoriamente la excepción de puntero nulo, por lo general funciona y en algún momento se bloquea, he buscado mucho pero no recibí ninguna ayuda, ya que no hay una línea adecuada desde donde obtengo ayuda.

También estoy usando el controlador con él.

El error de mi logcat es el siguiente y el código se agrega debajo,

Este es mi código de la siguiente manera, aquí generalmente se bloquea cuando se hace clic en el botón de registro o se olvida en la primera instalación y después de eso generalmente funciona bien, pero en algún momento me da un error.

Answer 1

Creo que el error vino de esta línea.

mySpannable.setSpan(touchableSpan, GeneralFunctions.getText(myTextView).indexOf("Register"), GeneralFunctions.getText(myTextView).length(), 0);

intente cerrar la sesión; obtendrá el valor de índice y el texto de vista de texto del método gettext (textview) e indexOf ().

Answer 2

No debe llamar a init() (o cualquier código que toque la interfaz de usuario de Android) en un subproceso que no sea de la interfaz de usuario.

Answer 3

Pruebe el método thread.join() , en el que está llamando al método init() .
