android - コードで Android 2.2 LinearLayout の高さを変更する

Question

コードを使用してレイアウトの高さを変更しようとしましたが、成功しませんでした。ここで見たすべての例と他のサイトを試しましたが、アプリがシャットダウンし続けます。

xml code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/main_lay"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >

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

<LinearLayout 
     android:layout_width="fill_parent"
     android:layout_height="50dp"
     android:background="@color/green">

    <ImageView
       android:layout_width="fill_parent"
       android:contentDescription="@string/desc"
       android:layout_height="45dp"
       android:layout_gravity="center_vertical|left"
       android:scaleType="fitStart"
       android:background="@color/orange"
       android:src="@drawable/logo"
       >
    </ImageView>

</LinearLayout>
</LinearLayout>

Java code:
main_layout=(LinearLayout)findViewById(R.id.main_lay);
main_layout.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));
main_layout.setBackgroundResource(R.color.white);

layout_add = (LinearLayout) findViewById(R.id.layout_add);
layout_add.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT,50 ));
layout_add.setBackgroundResource(R.color.dark_grey);

何が間違っているのか理解できません。私はそれを修正するためにさまざまな方法を試しました。Backround 設定は正常に機能しています。ニロ君ありがとう
