我正在创建一个图像测验应用....带有图像和4个单选按钮。图像通过ViewFlipper添加，选项和答案取自数据库。 该应用程序正在工作，但我无法加载结果页面，无法得到祝酒词＃34;干得好:)和＃34;即使答案是正确的。我无法追查问题，请帮帮我
这是我的MainActivity.java
public class MainActivity extends ActionBarActivity {

// Add all the images to the ViewFlipper
for (int i = 0; i < resources.length; i++) {

最后是ResultActivity.java
public class ResultActivity extends Activity {

setContentView(R.layout.activity_result);
//get rating bar object
RatingBar bar=(RatingBar)findViewById(R.id.ratingBar1);
//get text view
TextView t=(TextView)findViewById(R.id.textResult);
//get score
Bundle b = getIntent().getExtras();
int score= b.getInt("score");
//display score
bar.setRating(score);
switch (score)
{
case 1:
case 2: t.setText("Oopsie! Better Luck Next Time!");
break;
case 3:
case 4:t.setText("Hmmmm.. Someone's been reading a lot of trivia");
break;
case 5:t.setText("Who are you? A trivia wizard???");
break;
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
}
答案 0 :(得分：0)
检查
的输出 Log.d("yourans", currentQ.getANSWER() + " " + answer.getText());
验证它是你认为的......
