Horizo​​ntalScrollView中的Android布局具有相同的宽度

Question

我有一个垂直布局，在底部我有一个HorizontalScrollView。在ScrollView里面，我想显示四个容器，这些容器应该具有完全相同的宽度。 这些容器中的每一个都加载了一个片段，该片段使宽度和高度match_parent的布局膨胀。在发出一些网络请求之后，我只填充ScrollView内的容器，所以在加载所有数据后我可以这样：

first_small_container_data      -> width = 100px
second_small_container_data     -> width = 200px
third_small_container_data      -> width = 230px
fourth_small_container_data     -> width = 112px

我希望在加载数据后，HorizontalScrollView中的所有容器都具有所有最大宽度，在本例中为230px。

我尝试使用以下布局实现此目的，但没有成功。

如何仅使用XML解决此问题？

public class TestActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_hz);



        /* Load Data */

        // After data is loaded
        // Set containers to maximum width: 230px;
        int maxWidth = 230;

        LinearLayout firstSmallContainer = (LinearLayout) findViewById(R.id.first_small_container_data);
        LinearLayout secondSmallContainer = (LinearLayout) findViewById(R.id.second_small_container_data);
        LinearLayout thirdSmallContainer = (LinearLayout) findViewById(R.id.third_small_container_data);
        LinearLayout fourthSmallContainer = (LinearLayout) findViewById(R.id.fourth_small_container_data);

        firstSmallContainer.setLayoutParams(new LinearLayout.LayoutParams( maxWidth, 20));
        secondSmallContainer.setLayoutParams(new LinearLayout.LayoutParams( maxWidth, 20));
        thirdSmallContainer.setLayoutParams(new LinearLayout.LayoutParams( maxWidth, 20));
        fourthSmallContainer.setLayoutParams(new LinearLayout.LayoutParams( maxWidth, 20));

    }
