Android如何在文本视图或任何东西打印数组 [英] Android how to print a array in text view or anything

问题描述

我有一些单词，我想在单击按钮后在文本视图中将单词数组打印到屏幕上。我正在使用循环遍历整个列表，然后设置文本，但我一直得到一个错误，加上它只会取代最后一个值，所以它不会打印整个数组。如果有人可以向我解释如何做像g.drawSting（），但Android版本，这将是伟大的。我的代码rt现在不在我身边，但它是这样的：
- 我是一个初学者Android机器人顺便说一句，可能可以告诉这个问题，这一点。

<$ p

//代码只是按下一个按钮{
//去两个方法来修复私有数组$ {code $> public void onCreate（Bundle savedInstanceState）
{
for（int y = 0; y< = array.size（） - 1; y ++）{
textArea.setText（aarray.get（y））; //打印数组
}
}
}

解决方案

  int arraySize = myArray.size（）; 
 for（int i = 0; i< arraySize; i ++）{
 myTextView.append（myArray [i]）; 
 
 
 
 
 
 $ b如果你想逐一打印，那么使用\ n  p> 
 
 
  myTextView.append（myArray [i]）; 
 myTextView.append（\\\
）; 
  
 
I have a array of words and I would like to print the array of words onto the screen in a text view after a button is clicked. i was using a for loop to go through the whole list and then set text, but i keep getting a error with that plus it will just replace the last value, so it wont print the whole array. If anybody could explain to me how to do like a g.drawSting() but android version that would be great. my code rt now is not with me but it something like:
-I'm a beginner to android btw, probably could tell by this question tho.
public void onCreate(Bundle savedInstanceState)
{
//code for a button just being pressed{
 //goes to two methods to fix the private array{
     for(int y=0; y<=array.size()-1; y++){
        textArea.setText(aarray.get(y));   //prints all strings in the array
 }
}
}

解决方案
int arraySize = myArray.size();
for(int i = 0; i < arraySize; i++) {
myTextView.append(myArray[i]);
}
if you want to print one by one, then use \n
myTextView.append(myArray[i]);
myTextView.append("\n");
