您好，我正在做一個android測驗，當問題完成但轉到結果活動時，轉到結果活動

Question

我的項目代碼在此處給出，在此我想在問題結束后轉到結果活動。 僅在時間到了時才進行結果活動，而在問題結束時則沒有結果。 我應該在if（<20）行代碼中實現什么才能轉到結果頁面。

MyQuizActivity：

public class MyQuizActivity extends AppCompatActivity {

        private String mAnswer;

Answer 1

您添加了多個捆綁，所以我認為它不起作用。

 Intent intent = new Intent(MyQuizActivity.this,
                    ResultActivity.class);

            intent.putExtra("mScore", +mScore); //put score
            intent.putExtras("count_correct_answer", +count_correct_answer); // Put your Correct Answer score to your next
            intent.putExtras("count_wrong_answer", +count_wrong_answer); // Put your Wrong Answer score to your next
            startActivity(intent);

            finish();

Answer 2

僅在時間到了時才進行結果活動，而在問題結束時則沒有結果。

這是因為在活動開始時onCreate（）僅被調用一次，因此此代碼

if (mQuestionNumber< 20) {
         mQuestionView.setText(mQuestionBank.getQuestion(mQuestionNumber));

            //set all buttons Blue for next question
            mButtonChoice1.setBackgroundColor(Color.BLUE);
            mButtonChoice2.setBackgroundColor(Color.BLUE);
            mButtonChoice3.setBackgroundColor(Color.BLUE);
            mButtonChoice4.setBackgroundColor(Color.BLUE);
            updateQuestion();

}
else {
    Intent intent = new Intent(MyQuizActivity.this,
            ResultActivity.class);
    Bundle b = new Bundle();
    b.putDouble("mScore", mScore); // Your score
    intent.putExtras(b); // Put your score to your next
    startActivity(intent);
    finish();
}

僅在活動開始時運行，然后您才更新問題和選擇，否則其他部分實際上並未運行。

因此，您可以做的是檢查updateQuestion（）中的問題計數並從那里調用結果活動。

Answer 3

在開始之前使用finish() - startactivity(your intent) ..您的當前條件在啟動活動后完成了...
