Android stringbuilder元素 [英] Android stringbuilder elements

问题描述

大家好，

你会好像看看我的代码下面的代码并帮助

从stringbuilder中检索字符串。我想要做的是拆分stringbuilder，将其转换为字符串并获取第一个和第二个

元素，并将它们用作数据库的包输入。

提前感谢< br $>

Hello all,
would you be kind to have a look a look at the piece of my code bellow and help
with string retrieve from stringbuilder. What I want to do is split the stringbuilder, convert it to string and get the 1st and 2nd
element and use them as bundle input for database.
Thanks in advance

@Override
            public void onClick(View v) {
                  StringBuilder checkedcontacts= new StringBuilder();
                System.out.println(".............."+ma.mCheckStates.size());
                for(int i = 0; i < name1.size(); i++)

                    {
                    if(ma.mCheckStates.get(i)==true)
                    {
                                      	
                    	checkedcontacts.append(name1.get(i).toString());
                        checkedcontacts.append(" ");
                        checkedcontacts.append(phno1.get(i).toString());
       
                    }
                    else
                    {
                        System.out.println("Not Checked......"+name1.get(i).toString());
                    }

                    
                }

                Toast.makeText(Display.this, checkedcontacts,
                Toast.LENGTH_SHORT).show();

推荐答案

可能它应该像这样改变：

Probably it should change like this:

for(int i = 0; i < name1.size(); i++)

                    {
                    if(ma.mCheckStates.get(i)==true)
                    {

                        checkedcontacts.append(name1.get(i).toString());
                        checkedcontacts.append(" ");
                        checkedcontacts.append(phno1.get(i).toString());
                        break; // break your loop
                    }
                    else
                    {
                        System.out.println("Not Checked......"+name1.get(i).toString());
                    }


                }

                Toast.makeText(Display.this, checkedcontacts.toString(),
                Toast.LENGTH_SHORT).show(); // you didn't use toString()
