将 textView 动态添加到 linearLayout [英] Dynamically add textViews to a linearLayout
问题描述
我在这里的某个地方读到了这篇文章,我完全失去了它,但可以使用一些帮助.
I read this somewhere here and I totally lost it, but could use some assistance.
我的应用程序正在将列名从 sqlite 拉到一个数组中.我想创建一个文本视图并为每个文本编辑文本(通过数组的大小),我记得在某处读过您可以将 textViews 变量名称视为数组,但我不知道现在在哪里.
My app is pulling the column names from sqlite into an array. I want to create a textview and edit text for each one (via the size of the array), and I remember reading somewhere that you can treat the textViews variable names like an array, but I don't know where that is now.
那么我将如何为数组中的许多列表动态创建 textView 和 editText?
So how would I dynamically create a textView and editText for however many listings are in an array?
有点像
TextView tv[] = new TextView()...
for(...){
tv[i]...
}
是这样吗?
感谢您的帮助!
推荐答案
你需要的应该是这样的:
Something like the following should be what you need:
final int N = 10; // total number of textviews to add
final TextView[] myTextViews = new TextView[N]; // create an empty array;
for (int i = 0; i < N; i++) {
// create a new textview
final TextView rowTextView = new TextView(this);
// set some properties of rowTextView or something
rowTextView.setText("This is row #" + i);
// add the textview to the linearlayout
myLinearLayout.addView(rowTextView);
// save a reference to the textview for later
myTextViews[i] = rowTextView;
}
