我正在开发联系人应用程序,它添加了电子邮件地址、电话号码.我必须在代码本身中动态创建编辑文本.我不知道如何以及在哪里实现这个逻辑,建议任何帮助将不胜感激.
I'm developing Contact Application, which adds Email address, phone number. I have to create edit text dynamically in code itself. I don't know how and where to implement this logic, suggest any help would be grateful.
你可以这样创建:
EditText myEditText = new EditText(context); // Pass it an Activity or Context
myEditText.setLayoutParams(new LayoutParams(..., ...)); // Pass two args; must be LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, or an integer pixel value.
myLayout.addView(myEditText);
这可以在 UI 线程的任何地方实现;一个点击监听器,一个 onCreate
方法,以及介于两者之间的一切.
This can be implemented anywhere on the UI thread; a click listener, an onCreate
method, and everything in between.
在这个问题中有一个更通用的例子,以及这些流程的详细介绍在此博客中一个>.
There is a more generic example in this question, and a good rundown of these processes in this blog.
