Question

I have this main.xml:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:src="@drawable/ic_launcher"/>
    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="@android:color/white"
        android:orientation="horizontal" >   
        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="300dp"
            android:layout_height="wrap_content"
             android:background="@drawable/barslide" 
             android:layout_marginLeft="500dp"/>
    </LinearLayout>
</FrameLayout>

I want to create the same UI like in main.xml in java code. I try to code it but it doesn’t work, it’s not same as the xml. Here is the code:

void createUI(){

    LayoutParams params1 = new FrameLayout
    (LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);

    LayoutParams params2 = new android.widget.FrameLayout.LayoutParams(
    android.widget.FrameLayout.LayoutParams.FILL_PARENT,
android.widget.FrameLayout.LayoutParams.FILL_PARENT,
Gravity.BOTTOM);

FrameLayout f1 = new FrameLayout(this);
f1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));

LinearLayout l2 = new LinearLayout(this);
l2.setOrientation(LinearLayout.HORIZONTAL);
l2.setLayoutParams(params2);

view1 = new page1(getBaseContext());
view360 = view1.img1(getBaseContext());
view360.setBackgroundDrawable(getResources().getDrawable(R.drawable.black1));
view360.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));

slidebar = view1.img3(getBaseContext());
slidebar.setBackgroundResource(R.drawable.barslide);
slidebar.setLayoutParams(new LinearLayout.LayoutParams(300, LayoutParams.WRAP_CONTENT,Gravity.BOTTOM));


f1.addView(view360);
f1.addView(l2);
l2.addView(slidebar);

addContentView(f1, params1);
}

Your code doesn’t quite replicate the xml layout(this was to big for a comment):

            // replace THIS(from the constructors) with your context reference
    FrameLayout fl = new FrameLayout(this);
    fl.setLayoutParams(new FrameLayout.LayoutParams(
            FrameLayout.LayoutParams.MATCH_PARENT,
            FrameLayout.LayoutParams.MATCH_PARENT));
    ImageView imv1 = new ImageView(this); // the first ImageView
    imv1.setLayoutParams(new FrameLayout.LayoutParams(
            FrameLayout.LayoutParams.MATCH_PARENT,
            FrameLayout.LayoutParams.MATCH_PARENT));
    imv1.setImageResource(R.drawable.ic_launcher);
    fl.addView(imv1);
    LinearLayout ll = new LinearLayout(this);
    FrameLayout.LayoutParams llp = new FrameLayout.LayoutParams(
            FrameLayout.LayoutParams.MATCH_PARENT,
            FrameLayout.LayoutParams.WRAP_CONTENT);
    llp.gravity = Gravity.BOTTOM;
    ll.setLayoutParams(llp);
    ll.setBackgroundColor(Color.WHITE);
    ImageView imv2 = new ImageView(this); // the second ImageView
    DisplayMetrics metrics = getResources().getDisplayMetrics();
    float width = 300f;     
    int pWidth = (int) (metrics.density * width + 0.5f);
    LinearLayout.LayoutParams imvlp = new LinearLayout.LayoutParams(pWidth,
            FrameLayout.LayoutParams.WRAP_CONTENT);
    float margin = 500f;
    int pMargin = (int) (metrics.density * margin + 0.5f);
    imvlp.leftMargin = pMargin;
    imv2.setLayoutParams(imvlp);
    imv2.setBackgroundResource(R.drawable.food_image1);
    ll.addView(imv2);
    fl.addView(ll);

You’ll have to modify it to use your object page1(I don’t know exactly what are you trying to do there).
Also, are you sure you have to use the addContentView()(maybe setContentView?) method?(This method will add the views to the already present layout)
