在运行时我只显示一个文字Wrong_answer
。
public class AnswerActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_answer);
TextView textViewDisplayResult = (TextView) findViewById(R.id.text_view_display_result);
textViewDisplayResult.setText(getIntent().getExtras().getString("KEY_ALL_CHECKED"));
textViewDisplayResult.setText(getIntent().getBooleanExtra("KEY_ANSWER", false)?R.string.Good_answer:R.string.Wrong_answer);
}
POST UPDATE
public class MainActivity extends AppCompatActivity {
private static int NUMBER_OF_QUESTIONS = 3;
static boolean[] answer = new boolean[NUMBER_OF_QUESTIONS];
static boolean[] checked = new boolean[NUMBER_OF_QUESTIONS];
static boolean[] isAnswered = new boolean[NUMBER_OF_QUESTIONS];
final Intent intent = new Intent(MainActivity.this, AnswerActivity.class);
buttonCheckAnswer.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!allAnswersChecked())
intent.putExtra("KEY_ALL_CHECKED", R.string.text_not_checked);
else if (checkAnswers())
intent.putExtra("KEY_ANSWER", R.string.Good_answer);
else
intent.putExtra("KEY_ANSWER", R.string.Wrong_answer);
startActivity(intent);
}
});
public static void checkSelected() {
for (boolean radioChecked : checked) {
if (radioChecked) {
buttonCheckAnswer.setVisibility(View.VISIBLE);
break;
}
}
}
private boolean checkAnswers() {
for (boolean radioAnswer : answer) {
if (!radioAnswer) {
return false;
}
}
return true;
}
private boolean allAnswersChecked() {
for (boolean radioAnswer : isAnswered) {
if (!radioAnswer) {
return false;
}
}
return true;
}
和AnswerActivity
public class AnswerActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_answer);
TextView textViewDisplayResult = (TextView) findViewById(R.id.text_view_display_result);
textViewDisplayResult.setText(getIntent().getExtras().getString("KEY_ALL_CHECKED"));
textViewDisplayResult.setText(getIntent().getBooleanExtra("KEY_ANSWER", false)?getString(R.string.Good_answer):getString(R.string.Wrong_answer));
}
}

第二个setText
将覆盖您的第一个setText
值。
....
String x = getIntent().getExtras().getString("KEY_ALL_CHECKED");
textViewDisplayResult.setText(getIntent().getBooleanExtra("KEY_ANSWER", false) ? x +" "+ R.string.Good_answer: x +" "+ R.string.Wrong_answer);
答案 1 :(得分:0)
textViewDisplayResult将始终覆盖。 如果您希望两者都显示在同一个textView中,您只需要附加如下文本:
textViewDisplayResult.setText(getIntent().getExtras().getString("KEY_ALL_CHECKED"));
textViewDisplayResult.append(getIntent().getBooleanExtra("KEY_ANSWER", false)?getString(R.string.Good_answer):getString(R.string.Wrong_answer));
这将在同一textView中显示您的两个结果。
