java - 仅显示我的分数的最后数字

Question

我有一个按钮可以将我的积分发送到另一个 Activity :

public void nextButton(View view)
{
    Intent intent = new Intent(quiz_activity.this, score_activity.class);
    intent.putExtra("some_key", points);
    startActivity(intent);
}

在我的其他 Activity 中:

Bundle bundle = getIntent().getExtras();
        int point = bundle.getInt("some_key");

当我想在那里显示我的分数时，我会这样做

TextView scoreTextView = (TextView) findViewById(R.id.score);
        scoreTextView.setText("" + point);

当分数 <= 10 时，它工作正常，但当分数更高时，仅显示最后一个数字。 还有我的分数TextView:

抱歉，这是我的得分布局:

我在那里有我的单选按钮，当有人点击其中一个按钮时，如果他们回答正确，他们会得到 +2 分，如果回答不正确，他们会得到 -1 分。问题是当有人正确回答大多数问题，并且分数为 10+ 时..如果我有 16 分，它将显示 6 而不是 16。

这是应用程序的屏幕截图，我正确回答了所有问题，我的分数是 16，但它显示的是 6 Picture 1 Picture 2

我增加或减少我的分数的测验 Activity :

将下面的LinearLayout的layout_width更改为android:layout_width="match_parent"。

然后在同一个 LinearLayout 中，添加 android:gravity="center"。这会将 LinearLayout 中的 TextView 居中。

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:layout_gravity="center_horizontal">

        <TextView
            android:text="99"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/score"
            android:textSize="25sp"
            android:textColor="@color/colorAccent"/>

        <TextView
            android:text="/40"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/score1"
            android:textSize="25sp"
            android:gravity="center"/>
</LinearLayout>
