确保布局总是相同的大小

Question

我正在开发一个消息传递应用程序并且遇到了一个小问题，但却非常讨厌。我通过引入布局然后膨胀来动态渲染消息。这部分工作正常。问题是说我的消息短于另一条消息，较小的消息不保留布局以确保它与较大的消息大小相同。

我的布局文件如下所示

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:p1="http://schemas.android.com/apk/res/android"
p1:orientation="horizontal"
p1:minWidth="25px"
p1:minHeight="25px"

p1:layout_height="fill_parent"

                        p1:layout_marginRight="5dp"
                        p1:textColor="#000" />
                </LinearLayout>
            </LinearLayout>
        </LinearLayout>
    </LinearLayout>
    <LinearLayout
        p1:orientation="vertical"
        p1:minWidth="25px"
        p1:minHeight="25px"
        p1:layout_width="wrap_content"
        p1:layout_height="fill_parent"
        p1:id="@+id/linearLayout12"
        p1:layout_weight=".15" />
</LinearLayout>
</LinearLayout>

边框文件是这个

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
   <stroke android:width="1dip" android:color="@android:color/transparent"/>
</shape>

无论消息的大小如何，关于如何确保布局的任何想法都保持不变？
