Android: TextView ignores Gravity and Margin

Here is my code:

 //define tablerows. each table row has max 3 buttons
 LinearLayout llRow1 = (LinearLayout)findViewById(R.id.llRow1); llRow1.removeAllViews();

   float scale = getResources().getDisplayMetrics().density;
   int padding_5dp = (int) (5 * scale + 0.5f);

//Define FrameLayout
       FrameLayout flTmp = new FrameLayout(this);
       LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT, FrameLayout.LayoutParams.FILL_PARENT, 1f);
       lp.setMargins(0, 0, padding_5dp, padding_5dp);
       flTmp.setLayoutParams(lp);

//Add dynamically TextView
TextView tvTmp = new TextView(this);
tvTmp.setText("Test");
LinearLayout.LayoutParams tvPara=new LinearLayout.LayoutParams(
                            LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT );
tvPara.gravity = Gravity.BOTTOM | Gravity.LEFT;
tvPara.setMargins(padding_5dp, 0, 0, 0);
tvTmp.setLayoutParams(tvPara);

//Add dynamically Buttons for juice
    ImageButton btnTmp = new ImageButton(this);

[...]

//Add Button and TextView to FrameLayout
    flTmp.addView(btnTmp);
    flTmp.addView(tvTmp);

llRow1.addView(flTmp);

What i try to do is create an imagebutton dynamically with a textview description like following xml code:

<FrameLayout>
<ImageButton android:background="@null" android:id="@+id/button_x" android:layout_width="fill_parent" android:layout_height="fill_parent" android:scaleType="fitXY" android:src="@drawable/button_graphic"></ImageButton>    
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:clickable="false" android:text="TEST TEST"></TextView>
</FrameLayout>

works fine with my code, but the textview ignores margin and gravity parameters. its located on upper left corner without margins.

Any hint?

The LayoutParams you use need to be of the type of parent that the child is contained in. You're FrameLayout contains the TextView, but you're assigning a LinearLayout.LayoutParams reference to it. Make it a FrameLayout.LayoutParams or change to a LinearLayout. If I had to guess, it's silently catching this error and just ignoring it.
