Dans votre code, vous importaez SO Supprimer et ajoutez importer android.widget.relatelayAnt.layoutparams; au lieu de android.view.viewgroup.layoutparams
Importer android.widget.relatelayAnt.layoutparams;
Importer android.view.viewgroup.layoutparams
Pourquoi le point de vueGroup.LayoutParams ferait-ils une différence?
@Igorganapolsky parce que layoutAutparams est une classe intérieure de classes particulières.
Cliquez simplement sur CNT + O pour supprimer les importations indésirables
Vous devez rendre l'objet LayOutParams de la mise en page parent. Exemple dans la mise en page ci-dessous pour définir la hauteur et la largeur de la linearlayout, vous devez faire les aménagements de relativenifayout non linéarlayout même.
//IN ACTIVITY RelativeLayout.LayoutParams params=new RelativeLayout.LayoutParams(30,30); //Parent Params linearLayout.setLayoutParmas(params); //Child Layout //If you want to set the params of the Relative Layout above. It seems it doesn't have any parent but it has a parent created by android framework which is a frame layout. So FrameLayout.LayoutParmas params=new FrameLayout.LayoutParmas(30, 30);//FrameLayout is a parentcreated by anroid frame work relativeLayout.setLayoutParmas(params); ////Here Relative layout is child
Et c'est une bonne réponse.
Code d'utilisation ci-dessous:
imageView.setLayoutParams(
new android.widget.RelativeLayout.LayoutParams(
ViewPager.LayoutParams.MATCH_PARENT,
ViewPager.LayoutParams.MATCH_PARENT));
On dirait que vous modifiez le
LayoutParams dans le code. La mise en page XML seule ne causera pas cela. Donc, inclure le code pertinent dans la question.Assurez-vous d'importer les correctifs de layoutParams.
Mon erreur résolue avec la réponse de @kalyan PVS, merci pour vous aussi :)
@bukanamay bon, alors vous devez accepter sa réponse mec
