Q:

FrameLayout margin not working

My layout structure is like this
LinearLayout
    FrameLayout
       ImageView
       ImageView
    FrameLayout
    TextView
LinearLayout

I have set margin's for the two ImageView which are inside FrameLayout. But FrameLayout margins are discarded and it always set's the Image to top left corner. If i change from FrameLayout to LinearLayout the margin's work properly. How to handle this ? 
<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/inner1"
    >
        <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
        >

            <ImageView
             android:layout_width="24px" 
             android:layout_height="24px" 
             android:id="@+id/favicon"
             android:layout_marginLeft="50px"
             android:layout_marginTop="50px"
             android:layout_marginBottom="40px"
             android:layout_marginRight="70px"      

            />      
            <ImageView
             android:layout_width="52px" 
             android:layout_height="52px" 
             android:id="@+id/applefavicon" 
             android:layout_marginLeft="100px"
             android:layout_marginTop="100px"
             android:layout_marginBottom="100px"
             android:layout_marginRight="100px"              
            />

        </FrameLayout>  
            <TextView
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:id="@+id/title"                 
            android:layout_marginLeft="10px"        
            android:layout_marginTop="20px"
            android:textColor="#FFFFFF"  
            android:textSize = "15px"
            android:singleLine = "true"
            />

    </LinearLayout>

A:

I had the same issue myself and noticed that setting the layout_ margins does not work until you also set your ImageView's layout gravity i.e. android:layout_gravity="top" in the XML resource file, or from code: FrameLayout.LayoutParams.gravity = Gravity.TOP;.

A:

To make it more clear why. The FrameLayout.onLayout() call contains this (in api v2.3.4 at least):
    // for each child
    final LayoutParams lp = (LayoutParams) child.getLayoutParams();
    final int gravity = lp.gravity;
    if (gravity != -1) {
        // handle all margin related stuff

So if gravity is -1, there will be no margin calculation. And the thing is, gravity in FrameLayout.LayoutParams is defined by:
    gravity = a.getInt(com.android.internal.R.styleable.FrameLayout_Layout_layout_gravity, -1);

So if gravity is not set, there will be no margin calculation.

A:

add your xml this attribute and re run
android:layout_gravity="top"
everything is Ok!
and you dont set new layout params like this;
FrameLayout.LayoutParams llp = new FrameLayout.LayoutParams(WallpapersActivity.ScreenWidth/2, layH);

use like this:
FrameLayout.LayoutParams llp = (LayoutParams) myFrameLay.getLayoutParams();
llp.height = 100;
llp.width = 100;
myFrameLay.setLayoutParams(llp);
