How do I open a list view at a specific activity location?
I want to open the List view at the bottom of the screen to almost the mid-screen minimum. I have no idea how to do this. I only have an idea that this can only be done in a fragment and I don't know how to use it in my current activity and xml. What I want is shown in the following image:
Hope my question is perfectly clear. I know how to implement a list view, but I donβt know how to implement it in the way I wanted (I want to appear and disappear, breaking other views). this list should overlap other views.
EDIT
including my Xml file so that if you see what I did in design
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="content_desc_overlay"
android:src="@drawable/ic_launcher"
android:id="@+id/img_view"
/>
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/iv_overlay"
android:src="@drawable/doom"
android:scaleType="matrix"
/>
</FrameLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Open List"
android:id="@+id/btn_screenshot"
android:layout_gravity="right|top"
/>
</RelativeLayout>
Any suggestion? Source code would be appreciated. thank

put the list view in a separate blank activity and in the manifest put the activity topic in the dialog
<activity
android:name=".ui.activities.EditSignatureActivity"
android:label="@string/title_activity_edit_signature"
android:theme="@android:style/Theme.Holo.Light.Dialog" >
</activity>
and when the open list button is clicked, new intents start:
public void openListButton_OnClick(View v) {
Intent intent = new Intent(HomeActivity.this, List.class);
startActivity(intent);
}
remember to resize your new listView as much as you want it to be sized and add margins to match the position you want.

I'll give you a sample. You need to change. Ask if there is any doubt
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_marginTop="50dp"
android:id="@+id/top_row">
<LinearLayout
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Text A" />
</LinearLayout>
<LinearLayout
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Text B" />
</LinearLayout>
</LinearLayout>
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/top_row"
android:layout_marginBottom="15dp"
android:layout_marginLeft="30dp"
android:layout_marginRight="30dp"
android:layout_marginTop="15dp"></ListView>
</RelativeLayout>
Note. You need to load a listView with data.
