Мое приложение состоит из уровня, на каждом уровне 10 вопросов. Это мой первый уровень и первый класс вопросов ..Мое приложение, к сожалению, остановилось, возможно, из-за ошибок
public class level1 extends ActionBarActivity {
private EditText mans1;
private TextView mcount;
int sum;
public void Onclick(View v) {
mans1 = (EditText) findViewById(R.id.ans1);
mcount = (TextView) findViewById(R.id.count);
double answer = Double.parseDouble(mans1.getText().toString());
if (answer == (8 + 7))
{
Toast.makeText(level1.this, "الإجابة صحيحة", Toast.LENGTH_LONG).show();
mcount.setText(sum++);
}
else
{
Toast.makeText(level1.this, "الإجابة خاطئة", Toast.LENGTH_LONG).show();
mcount.setText(sum);
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_level1);
final TextView texview = (TextView)findViewById(R.id.count);
Button sendButton = (Button)findViewById(R.id.tm);
sendButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int count = Integer.parseInt(texview.getText().toString());
Intent intent = new Intent(getApplicationContext(), level1.class);
intent.putExtra("mycount", sum);
startActivity(intent);
}
});
}
public void buttonOnClickgo(View v) {
Button next = (Button) v;
startActivity(new Intent(getApplicationContext(), level1q2.class));
}
public void buttonOnClickBack(View v) {
Button back = (Button) v;
startActivity(new Intent(getApplicationContext(), Activity2.class));
}
}
и это первый класс вопросов второго уровня.
public class level1q2 extends ActionBarActivity {
private EditText mans1;
private TextView mcount;
int sum;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_level1q2);
TextView textView = (TextView)findViewById(R.id.count);
Intent intent = getIntent();
int count = intent.getIntExtra("mycount", 0);
textView.setText(count);}
public void Onclick(View view)
{
mans1 = (EditText) findViewById(R.id.ans1);
mcount = (TextView) findViewById(R.id.count);
double answer = Double.parseDouble(mans1.getText().toString());
if (answer == (15-3)) {
Toast.makeText(level1q2.this, "الإجابة صحيحة", Toast.LENGTH_LONG).show();
int count = getIntent().getIntExtra("mycount", 0);
mcount.setText(count++);
} else {
Toast.makeText(level1q2.this, "الإجابة خاطئة", Toast.LENGTH_LONG).show();
int count = getIntent().getIntExtra("mycount", 0);
mcount.setText(count);
}
}
public void buttonOnClickgo(View v) {
Button next = (Button) v;
startActivity(new Intent(getApplicationContext(), level1q3.class));
}
public void buttonOnClickBack(View v) {
Button back = (Button) v;
startActivity(new Intent(getApplicationContext(), Activity2.class));
}
}
Я сделал некоторые изменения в этих классах, потому что я хочу передать переменную count из первого вопроса во второй вопрос.
Он работал, прежде чем я редактировал их, но теперь он показывает «к сожалению, остановил» сообщение ..

Вам нужно отредактировать свой вопрос, чтобы дать конкретную ошибку, которая происходит, с трассировкой стека, если это возможно. – Bobulous
, пожалуйста, используйте отладчик и присоедините трассировку стека к вашему вопросу. – Basil
Есть ли причина, по которой вы создаете экземпляр этого дважды (TextView) findViewById (R.id.count); в методах onClick и onCreate в level1 и снова в классах levelq2? – Want2bExpert
