How to use addContentView?

Hi guys

i want Add an additional content view to the screen. Added after any existing ones in the screen -- existing views are NOT removed.

for example :

EditText c = new EditText(this);
this.addContentView(c, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

but my layout is not load from layout.xml, it was created myself

myView = new MyView(this);
setContentView(myView);

in this view add the contents any time i want or delete it

Hi!

Looks like that I had quite the same problem like you ... it's simply not working to replace the whole content with "this.setContentView(view)" (uuuhh ... or at least I had some problems with it).

I'm going to show you what I've done ... I'm not creating the second view (for result-displaying in my case) in runtime but I'm switching between two views by showing and hinding them.

my "main.xml":

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

        <LinearLayout
 
        id="@+id/mainlayout"
 
        android:orientation="vertical"
 
            android:layout_width="fill_parent"
 
            android:layout_height="wrap_content"
 
            >
 
            <!-- More Content here -->
 
        </LinearLayout>
 
        <LinearLayout
 
            id="@+id/resultlayout"
 
            android:orientation="vertical"
 
            android:layout_width="fill_parent"
 
            android:layout_height="wrap_content"
 
            >
 
            <!-- More Content here -->
 
        </LinearLayout>
 
</LinearLayout>

Ok, I have defined my two views/layouts in main.xml ... on startup "mainlayout" will be displayed and should be replaced by "resultlayout". In fact I'm just hiding "mainlayout" and displaying "resultlayout".

    private void generateMainView() {
 
        LinearLayout mainLayout = (LinearLayout)findViewById(R.id.mainlayout);
 
        LinearLayout resultLayout = (LinearLayout)findViewById(R.id.resultlayout);
 
        // Enable Main & Disable Result
 
        resultLayout.setVisibility(View.GONE);
 
        mainLayout.setVisibility(View.VISIBLE);
 
    }
 
    private void generateResultView() {
 
        LinearLayout mainLayout = (LinearLayout)findViewById(R.id.mainlayout);
 
        LinearLayout resultLayout = (LinearLayout)findViewById(R.id.resultlayout);
 
        // Enable Main & Disable Result
 
        resultLayout.setVisibility(View.VISIBLE);
 
        mainLayout.setVisibility(View.GONE);
 
    }

This works fine for me but I guess it wouldn't probably fit for you.

I've not tested it but you could try the following ...

1. Get the mainLayout like I did.

2. Try to add you "additional" view to the "mainLayout".

mainLayout.addView(child);

Could probably work
