Every time I forget it, write it down and find it easily. The code is copied from the current project. First, let's get a relativelayout

 
 

  
  
Private void setlistpath (context, relativelayout footerrelativelayout, string buttontext ){
  
  
If (flagaddfooterguide ){
  
  
// My music buttons
  
  
Imageview mymusic = new imageview (context );
  
  
Mymusic. setimageresource (R. drawable. style#mymusic );
  
  
Mymusic. setonclicklistener (New onclicklistener (){
  
  
@ Override
  
  
Public void onclick (view v ){
  
  
// Todo auto-generated method stub
  
  
(Mymusicactivity) mycontext). setsdcardflag (false );
  
  
(Mymusicactivity) mycontext). oncreate (null );
  
  
}
  
  
 
  
  
});
  
  
Mymusic. setid (1); // Set ID to 1
  
  
 
  
  
Imageview mystorage = new imageview (context );
  
  
Mystorage. setimageresource (R. drawable. style1_mymusic_usbstore );
  
  
Mystorage. setonclicklistener (New onclicklistener (){
  
  
 
  
  
@ Override
  
  
Public void onclick (view v ){
  
  
// Todo auto-generated method stub
  
  
// Set listview to display
  
  
(Mymusicactivity) mycontext). setlistviewlinearlayoutvisible (false );
  
  
// Galleryvisible is hidden
  
  
(Mymusicactivity) mycontext). setgalleryvisible (true );
  
  
}
  
  
 
  
  
});
  
  
 
  
  
Mystorage. setid (2); // Set ID to 2
  
  
// Set the button for the local current directory
  
  
Myimagebutton myimagebuttonfoldernow = new myimagebutton (context, R. drawable. style+mymusic_details, buttontext );
  
  
 
  
  
Relativelayout. layoutparams lp1 = new relativelayout. layoutparams (viewgroup. layoutparams. wrap_content,
  
  
Viewgroup. layoutparams. wrap_content );
  
  
Lp1.addrule (relativelayout. align_parent_left );
  
  
 
  
  
Relativelayout. layoutparams lp2 = new relativelayout. layoutparams (viewgroup. layoutparams. wrap_content,
  
  
Viewgroup. layoutparams. wrap_content );
  
  
Lp2.addrule (relativelayout. right_of, 1); // on the right of the control whose ID is 1
  
  
 
  
  
Relativelayout. layoutparams lp3 = new relativelayout. layoutparams (viewgroup. layoutparams. wrap_content,
  
  
Viewgroup. layoutparams. wrap_content );
  
  
Lp3.addrule (relativelayout. right_of, 2 );
  
  
 
  
  
Footerrelativelayout. addview (mymusic, lp1 );
  
  
Footerrelativelayout. addview (mystorage, lp2 );
  
  
 
  
  
// Play button
  
  
Myimagebutton myimagebuttonplay = new myimagebutton (context, R. drawable. mymusic_button_pause_backgroud, "play ");
  
  
 
  
  
Footerrelativelayout. addview (myimagebuttonfoldernow, lp3 );
  
  
 
  
  
Myimagebuttonplay. setid (4 );
  
  
Relativelayout. layoutparams lp4 = new relativelayout. layoutparams (viewgroup. layoutparams. wrap_content,
  
  
Viewgroup. layoutparams. wrap_content );
  
  
 
  
  
Lp4.addrule (relativelayout. left_of, 5 );
  
  
 
  
  
// Random button
  
  
Myimagebutton myimagebuttonplayrandom = new myimagebutton (context, R. drawable. mymusic_button_play_random, "random on ");
  
  
 
  
  
Myimagebuttonplayrandom. setid (5 );
  
  
Relativelayout. layoutparams lp5 = new relativelayout. layoutparams (viewgroup. layoutparams. wrap_content,
  
  
Viewgroup. layoutparams. wrap_content );
  
  
Lp5.addrule (relativelayout. left_of, 6 );
  
  
 
  
  
// Lyrics button
  
  
Myimagebutton myimagebuttonlyric = new myimagebutton (context, R. drawable. mymusic_button_lyric, "LRC lyrics ");
  
  
Myimagebuttonlyric. setid (6 );
  
  
Relativelayout. layoutparams lp6 = new relativelayout. layoutparams (viewgroup. layoutparams. wrap_content,
  
  
Viewgroup. layoutparams. wrap_content );
  
  
Lp6.addrule (relativelayout. align_parent_right );
  
  
// Add
  
  
Footerrelativelayout. addview (myimagebuttonlyric, lp6 );
  
  
Footerrelativelayout. addview (myimagebuttonplayrandom, lp5 );
  
  
Footerrelativelayout. addview (myimagebuttonplay, lp4 );
  
  
Flagaddfooterguide = false;

Super. oncreate (icicle );
  
  
Linearlayout layout = new linearlayout (this );
  
  
Layout. setorientation (linearlayout. Vertical );
  
  
 
  
  
BTN = new button (this );
  
  
BTN. setid (101 );
  
  
BTN. settext ("test logoff ");
  
  
BTN. setonclicklistener (this );
  
  
Linearlayout. layoutparams Param =
  
  
New linearlayout. layoutparams (100,50 );
  
  
Param. topmargin = 10;
  
  
Layout. addview (BTN, Param );
  
  
 
  
  
Btn2 = new button (this );
  
  
Btn2.setid (102 );
  
  
Btn2.settext ("exit ");
  
  
Btn2.setonclicklistener (this );
  
  
Layout. addview (btn2, Param );
  
  
 
  
  
TV = new textview (this );
  
  
TV. settextcolor (color. White );
  
  
TV. settext ("");
  
  
// FP is final int fp = linearlayout. layoutparams. fill_parent;
  
  
// Final int WC = linearlayout. layoutparams. wrap_content;
  
  
Linearlayout. layoutparams param2 =
  
  
New linearlayout. layoutparams (FP, WC );
  
  
Param2.topmargin = 10;
  
  
Param2.setmargins (0, 0, 5, 0); // The parameters are (INT left, int top, int right, int bottom)
  
  
Layout. addview (TV, param2 );
  
  
Setcontentview (layout );
 
 

Remember that the created parameter addview must be the sub-control parameter, not the container parameter. This is very important and I have wasted a lot of time here. If you need to add parameters to this layout, you can use layout. setlayoutparams (xxx Params) and layout. setxxx.
