I have a relative layout having children(3 buttons and edittext). Initially the layout is placed at bottom of the parent layout which is a linear layout. On click of one of the buttons I position it on top of the screen(parent linear layout), I am able to achieve this. But on click of another button i want it to be at original position again ie at bottom of the screen. Any help please. Here is the xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

On clicking reply_button I position the relative layout "post_layout" at top of screen, I am able to do this, but on clicking of post_cancel_button I want the relative layout "post_layout" to be positioned at bottom of screen again. here is the code which I am using to push layout to top of screen:
RelativeLayout.LayoutParams rparams = (RelativeLayout.LayoutParams) mPostLayout.getLayoutParams();
rparams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
mPostLayout.setLayoutParams(rparams);
Code for buttons:
mReplyButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
RelativeLayout.LayoutParams rparams = (RelativeLayout.LayoutParams) mPostLayout.getLayoutParams();
rparams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
mPostLayout.setLayoutParams(rparams);
InputMethodManager imm = (InputMethodManager)getSystemService(
Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(mUpdateEditView, InputMethodManager.SHOW_FORCED);
}
});
mMessageReplyCancelButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
RelativeLayout.LayoutParams rparams = (RelativeLayout.LayoutParams) mPostLayout.getLayoutParams();
rparams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
mPostLayout.setLayoutParams(rparams);
}
});
mPostLayout is name of relative layout I want to position, post_layout from xml
