我正在创建一个简单的应用程序，用户可以在其中获得问题并选择答案（radiobuttons），并在下一个活动中显示他们的分数，问题是它没有显示正确的分数..
我的quiz_layout中有一些问题和答案：

当用户回答所有问题时，它说他们有6分，而他们实际上有16分。
以下是应该显示的score_layout：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_height="match_parent"
android:layout_width="fill_parent"
android:layout_marginBottom="20dp"
android:layout_marginEnd="20dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_marginStart="10dp"
android:layout_marginTop="20dp"
android:layout_below="@id/toolbar1"
android:orientation="vertical"
android:gravity="center_vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Vaš rezultat na ovom testu je:"

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:textColor="@color/colorAccent"/>
<TextView
android:text="/16"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/score1"
android:textSize="25sp"
android:gravity="center"/>
</LinearLayout>
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/all_rights"
android:id="@+id/textView"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
还有score_activity我从Quiz_activity发送Bundle并在我的TextView中显示它：
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
public class score_activity extends AppCompatActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.score_layout);
Bundle bundle = getIntent().getExtras();
int points = bundle.getInt("some_key");
TextView scoreTextView = (TextView) findViewById(R.id.score);
scoreTextView.setText(String.valueOf(points));
}
}
我尝试了很多东西，但没有任何效果......
