How to disable the double click of a button?

  • 772

I have the following function to save data in a database, where "SaveData" is the onClick method of my button, but I want it to disable the button after clicking 1 time on it, to avoid saving all the time, my function is this one and I thought it was done with the onclicklistener thing but I see that it's not...:

public void GuardarDatos(View view) {

    int primero = Integer.parseInt(Primero1.getText().toString());
    finalizar =(ImageButton) findViewById(R.id.Guardar) ;

    BaseHelper baseHelper = new BaseHelper (this,"DEMODB",null,1);
    SQLiteDatabase db = baseHelper.getWritableDatabase();

    if(db!=null){

        ContentValues registronuevo = new ContentValues();

        registronuevo.put("Primero",primero);

        long i = db.insert("Notas",null,registronuevo);
        if ( i>0)
            Toast.makeText(this,"Puntuación guardada",Toast.LENGTH_SHORT).show();

        finalizar.setOnClickListener(new View.OnClickListener() {
            @Override   
            public void onClick(View v){
                onStop();  //Se supone que esto basta pero no. No funciona
            }
        });
    }

}

UPDATE:

finalizar = (ImageButton) findViewById(R.id.Guardar);

     finalizar.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View view) {
                //ejecuta el método
                GuardarDatos(); // --> Aquí me obliga a pasarle algo , 
                               // pone : The method GuardarDatos(View) in the type Tiempoacabadobebe is not applicable for the arguments () 
                //Deshabilita el botón
                finalizar.setEnabled(false); 
            }

        });

    Write this down:

    finalizar.setEnabled(false);

    I recommend you do it this way:

    ImageButton boton= (ImageButton) findViewById(R.id.button1);

        boton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View view) {
                //ejecuta el método
                guardarDatos();
                //Deshabilita el botón
                boton.setEnabled(false); 
            }

        });
        return true;
    }
public void guardarDatos(){
//cosas que quieres que haga el botón al clickearlo
}

    Where button is the imagebutton, yours is called finish .

  2. public void GuardarDatos(View view) {

int primero = Integer.parseInt(Primero1.getText().toString());
finalizar =(ImageButton) findViewById(R.id.Guardar) ;

BaseHelper baseHelper = new BaseHelper (this,"DEMODB",null,1);
SQLiteDatabase db = baseHelper.getWritableDatabase();

if(db!=null){

    ContentValues registronuevo = new ContentValues();

    registronuevo.put("Primero",primero);

    long i = db.insert("Notas",null,registronuevo);
    if ( i>0)
        Toast.makeText(this,"Puntuación guardada",Toast.LENGTH_SHORT).show();

    finalizar = (Button)findViewById(R.id.finalizar); finalizar.setClickable(false);
} }

    Be careful with the findViewById, the one I have put is an example, I don't know what the id of your button will be, and here too, be careful, I don't know if you are using button or AppCompatButton, otherwise I remember that's what it's called

  3. It is important to ensure that the reference of the button to which you will assign it listeneris correct,

    finalizar = (ImageButton) findViewById(R.id.Guardar);

    for the click to work correctly and the instruction to disable the button on click.

    finalizar = (ImageButton) findViewById(R.id.Guardar);
   finalizar.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View view) {
                //ejecuta el método
                GuardarDatos(); 
                //Deshabilita el botón
                finalizar.setEnabled(false); 
            }
             return true;
        });

  4. Colleagues, I found this solution in a previous forum. And it is simpler than setEnable(true/false), since sometimes it is difficult to capture the view of the button that you want to enable.

    Declaration of Variables:

    ...
private static final long TIEMPO_MINIMO= 1000; // Minimo de espera para click
private long ultimoClick= 0; // Fecha del Ultimo click capturado
...

    And finally we put these 5 lines where we want to avoid the double click:

    // Evitar doble click boton
if (SystemClock.elapsedRealtime() - ultimoClick < TIEMPO_MINIMO){
    return;
}
ultimoClick= SystemClock.elapsedRealtime();

    For example I put it inside the onClick method:

    ...
    @Override
    public void onClick(View v) {
        // Evitar doble click boton
        if (SystemClock.elapsedRealtime() - ultimoClick < TIEMPO_MINIMO){
            return;
        }
        ultimoClick= SystemClock.elapsedRealtime();
...

  5. button.setEnable(false);

    with this it is more than enough to be able to deactivate the click on a button. :D
