android–EditText的大小不适合内容

概述我对动态创建的EditText有一点问题,我通过我创建的小键盘输入文本,取代原来的Android.文本是使用append插入的,但EditText的大小不适合文本.为什么？使用此解决方案：EditTextet=newEditText(myContext);LayoutParamsparams=newLayoutParams(LayoutParams.WRAP_CONTENT,L

我对动态创建的EditText有一点问题,我通过我创建的小键盘输入文本,取代原来的Android.文本是使用append插入的,但EditText的大小不适合文本.为什么？

使用此解决方案：

EditText et = new EditText(myContext);LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); et.setLayoutParams(params);

我有这个错误：

解决方法:

import androID.Widget.linearLayout.LayoutParams;

将参数添加到WRAP_CONTENT.并设置所需的高度布局,填充或包裹.第一个是宽度,第二个是高度.

 EditText et = new EditText(myContext); LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); et.setLayoutParams(params);
