我正在制作一个测验应用。我创建了一个方法updateQuestion（），它接受一个随机整数来显示数组中的问题。我遇到的问题是，当用户点击按钮时，它第一次正常工作。当弹出第二个问题时，按钮不会听取答案。在重复点击时，按钮有时会工作。请帮忙，抱歉英语不好
更新问题代码 -
public void updateQuestion(int num){
dpText.setText(mdata.getQues(num));
button1.setText(mdata.getAlia(num));
button2.setText(mdata.getPari(num));
correctAnswer = mdata.getAnswer(num);
}
游戏代码 -
private void gameOver(){
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder
.setMessage("Game Over")
.setCancelable(false)
.setPositiveButton("New Game",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
startActivity(new Intent(getApplicationContext(), MainActivity.class));
finish();
}
})
.setNegativeButton("Exit",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
}
