La taille de l'EditText ne correspond pas au contenu

Question

J'ai un petit problème avec le EditText créé dynamiquement où je saisis du texte via un petit clavier que j'ai créé, en remplacement de l'original Android. Le texte est inséré avec l'ajout, mais la taille de EditText ne correspond pas au texte. Pourquoi?

avec cette solution:

EditText et = new EditText(myContext); 

LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 

et.setLayoutParams(params); 

J'ai cette erreur:

Answer 1

import android.widget.LinearLayout.LayoutParams; 

Ajoutez le paramètre à WRAP_CONTENT. Et également définir la disposition de hauteur souhaitée, remplir ou envelopper. Le premier est la largeur, le second est la hauteur.

EditText et = new EditText(myContext); 

LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 

et.setLayoutParams(params);
