    <p>Im having problems with this... Note that tip.setText tells me that it's higher than 0. I will also call getResults method in another class. (Int 'correct' is already higher than 0)</p> <p>I'd like to know why correct is always 0 in getResults and how can I fix that?</p> <pre><code> public int correct = 0; private String[] questions = {"Question 1", "Question 2", "Question 3", "Question 4", "Question 5" }; public void onClick(View view) { if (alive == false) { // startActivity(new Intent("com.aleksei.etb.END")); return; } try { button_click = MediaPlayer.create(this, R.raw.button_click); button_click.start(); switch(view.getId()){ case R.id.button5: //main break; case R.id.button1: //answer_1 if(correct(1)) correct++; break; case R.id.button2: //answer_2 if(correct(2)) correct++; break; case R.id.button3: //answer_3 if(correct(3)) correct++; break; case R.id.button4: //answer_3 if(correct(4)) correct++; break; default: break; } Game(i1); tip.setText("Correct answers "+correct); //this thing tells me that it's not 0.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
