here is the code-
FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) searchPin.getLayoutParams();
params.setMargins(135, 176, 0, 0);
//params.leftMargin = 135; // also not worked
//params.topMargin = 376;
searchPin.setLayoutParams(params);
Where ever, from xml its working-
android:layout_marginLeft="135dp"
what can be the reason? am i missing something!
-thnx
Try this:
params.gravity = Gravity.TOP;
I had a FrameLayout child of a RelativeLayout so the framework was trying to cast FrameLayout params to RelativeLayout, I solved this way
FrameLayout mylayout = (FrameLayout) view.findViewById(R.id.mylayout);
ViewGroup.MarginLayoutParams params = (MarginLayoutParams) mylayout.getLayoutParams();
params.setMargins(1, 2, 3, 4);
mylayout.setLayoutParams(params);
I think what you're missing is that, when you set programmatically the parameters for an element, those parameters are provided actually to the parent View, so that it knows how to position the element. The parameters are not set back to the element itself. Consider the following code example. Also note, that the layout parameters are of the type of the parent.
LinearLayout linearLayout = new LinearLayout(this);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(6,6,6,6);
Button someButton=new Button(this);
someButton.setText("some text");
linearLayout.addView(someButton, layoutParams);
simple solution-
searchPin = (ImageView) findViewById(R.id.waypts_search_pin);
searchPin.setPadding(135, 176, 0, 0);
You can try this
FrameLayout.LayoutParams srcLp = (FrameLayout.LayoutParams)searchPin.getLayoutParams();
FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(srcLp.width, srcLp.height, srcLp.gravity);
lp.setMargins(srcLp.leftMargin, srcLp.topMargin, srcLp.rightMargin, srcLp.bottomMargin);
searchPin.setLayoutParams(lp);
Just use LayoutParams instead of FrameLayout.LayoutParams
LayoutParams params = (LayoutParams) searchPin.getLayoutParams();
params.setMargins(135, 176, 0, 0);
searchPin.setLayoutParams(params);
this worked for me
