Question

我有一份案文文件,我正在从我的SD卡中取出,该卡片载有一阵式便衣。这里是该档案的内容......

http://www.oddree.com/rayhaque/android1.jpg,http://www.oddree.com/rayhaque/android2.jpg,http://www.oddree.com/rayhaque/android3.jpg,http://www.oddree.com/rayhaque/android4.jpg,http://www.oddree.com/rayhaque/android5.jpg

我正试图将这一案文输入一个强硬体,将它变成一个阵列,然后把该阵列装成一个名单改编器。如果我试图把读写成或读写成一个微不足道的结果,我就会被迫随时关闭。如果我把档案内容抄录为“长处”,然后使用......一切照旧。

因此,从文字档案中装载这种 st子与从包括舱面上加载两者之间有何区别? 它是一成不变的问题吗?

这里是我的法典。我注意到了什么是行之有效的,什么是失败的。

public class MainActivity extends Activity {

ListView list;
LazyAdapter adapter;
List<String> strings = new ArrayList<String>();
String readString = new String();
String arrayNBOW;

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    try{
     File f = new File(Environment.getExternalStorageDirectory()+"/LazyList/gkindex.txt");
     FileInputStream fileIS = new FileInputStream(f);
     BufferedReader buf = new BufferedReader(new InputStreamReader(fileIS));

     while((readString = buf.readLine())!= null){
      String arrayNBOW = readString.trim();
      Toast.makeText(MainActivity.this, "STARTUPPULL: "+arrayNBOW, Toast.LENGTH_LONG).show();
     }
  } catch (FileNotFoundException e) {
   Toast.makeText(MainActivity.this, "FAIL: "+e, Toast.LENGTH_LONG).show();
   e.printStackTrace();
  } catch (IOException e){
   Toast.makeText(MainActivity.this, "FAIL: "+e, Toast.LENGTH_LONG).show();
   e.printStackTrace();
  }

    setContentView(R.layout.main);
    list=(ListView)findViewById(R.id.list);

    String testArray = "http://www.oddree.com/rayhaque/android1.jpg,http://www.oddree.com/rayhaque/android2.jpg,http://www.oddree.com/rayhaque/android3.jpg";

    // THIS FAILS
    // String[] testArraySplit = TextUtils.split(arrayNBOW, ",");

    // THIS WORKS
    String[] testArraySplit = TextUtils.split(testArray, ",");

    adapter=new LazyAdapter(this, testArraySplit);
 list.setAdapter(adapter);

    Button b=(Button)findViewById(R.id.button1);
    b.setOnClickListener(listener);

    Button c=(Button)findViewById(R.id.button2);
    c.setOnClickListener(loadtext);

}

事先感谢你向我提供的任何建议或协助!

public class MainActivity extends Activity {

ListView list;
LazyAdapter adapter;
List<String> strings = new ArrayList<String>();
String readString = new String();
String arrayNBOW;
String[] nardsArray;
String nards;

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

/ 新的解决办法

  File sdcard = Environment.getExternalStorageDirectory();
  File file = new File(sdcard,"/LazyList/gkindex.txt");
  StringBuilder text = new StringBuilder();

  try {
      BufferedReader br = new BufferedReader(new FileReader(file));
      String line;

      while ((line = br.readLine()) != null) {
          text.append(line);
          text.append( 
 );
          nards = text.toString();
          nardsArray = TextUtils.split(nards, ",");
      }
  }
  catch (IOException e) {
      Toast.makeText(MainActivity.this, "FAIL: "+e, Toast.LENGTH_LONG).show();
  }

/ 最终新解决方案

    Toast.makeText(MainActivity.this, "FILE-READ: "+nardsArray, Toast.LENGTH_LONG).show();

    setContentView(R.layout.main);
    list=(ListView)findViewById(R.id.list);

    adapter=new LazyAdapter(this, nardsArray);
    list.setAdapter(adapter);

    Button b=(Button)findViewById(R.id.button1);
    b.setOnClickListener(listener);

    Button c=(Button)findViewById(R.id.button2);
    c.setOnClickListener(loadtext);

}

我怀疑你们的读物没有工作。首先,我注意到,没有关于关闭溪流的最后条款。第二是,你在案卷结束前再行。如果你在那里有一条空线的话? 单线“”检查。您还应打破内容的第一行。

此外,我更喜欢使用一个像

这是否有助于?
