我的应用程序不幸停止可能是由于错误

标签： java android

我的应用程序由级别组成，每个级别有10个问题。这是我的第一级和第一级问题.. 

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));
}

}

这是第一级第二级问题。

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));
}

}

我在这些类中做了一些更改，因为我想将count变量从第一个问题传递到第二个问题活动。

在我编辑它们之前它正在工作，但现在它显示“不幸停止”的消息..

请查看代码

调试后..

问题正是你的例外所说的：

您的按钮是一个ImageButton，但您尝试将其强制转换为Button（不是ImageButton的超类）。
