LinearLayout加载动态view时显示不全解决办法

问题：在某个主要Layout里面有个LinearLayout，用来动态加载别的view页面，若是须要加载的动态view内容很空洞(例如没有足够的Text长度来撑起整个layout宽度)，这时候这个被加载的view就会不能以fill_parent的width来显示。

如图：

实际想要的效果为：

java code：

 public class TestActivity extends Activity {
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
         View view = getLayoutInflater().inflate(R.layout.test, null);
         layout.addView(view);
     }
 }

main 布局：

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:background="#fff"
     android:orientation="vertical" >

     <LinearLayout
         android:id="@+id/layout"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent" >
     </LinearLayout>

 </LinearLayout>

test 布局：

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:background="#fff"
     android:orientation="vertical" >

     <TextView
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:text="测试页面" />

     <LinearLayout
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:layout_margin="5dip"
         android:orientation="horizontal" >

         <TextView
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="帐号：" />

         <EditText
             android:layout_width="fill_parent"
             android:layout_height="wrap_content" />
     </LinearLayout>

     <LinearLayout
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:layout_margin="5dip"
         android:orientation="horizontal" >

         <TextView
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="密码：" />

         <EditText
             android:layout_width="fill_parent"
             android:layout_height="wrap_content" />
     </LinearLayout>

 </LinearLayout>

解决办法：

在动态view的添加代码前定义一个LayoutParams，而后在添加view时明肯定义一下这个view的LayoutParams

 public class TestActivity extends Activity {
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
         View view = getLayoutInflater().inflate(R.layout.test, null);
         LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
         layout.addView(view, params);
     }
 }
