如何获取微调器选定项目的文本？

当我点击保存按钮时,我必须在我的微调器中选择项目上的文本.我需要的文字不是索引.

如果存在于给定索引的ArrayList中,如何替换元素？

如何将布局方向修改为纵向,并且在运行时不允许从纵向更改为横向？

在Java中如何将InputStream读取/转换为字符串？

嗨,我想把这个BufferedInputStream放到我的字符串中,我该怎么做？

BufferedInputStream in = new BufferedInputStream(sktClient.getInputStream() );
String a= in.read();

这意味着什么,有什么区别？

我应该在Runnable Run方法中写什么来取消Alert.Bulider？

AlertDialog.Builder ad;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Context context=this;
     ad = new AlertDialog.Builder(context);
        ad.setTitle("Warning");
        ad.setMessage("Just Testing It");

        ad.setPositiveButton("Yes", new OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub

            }
        });

        ad.setNegativeButton("Nooooo", new OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub

            }
        });

        ad.show();
        Handler h=new Handler();
        h.postAtTime(r, 10000);

    }
    public Runnable r=new Runnable() {

        @Override
        public void run() {

通过使用apache POI如何将ms word文件转换为pdf？

我使用以下代码,但它没有工作给出错误,我想我正在导入错误的类？

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.OutputStream;

import org.apache.poi.poifs.filesystem.POIFSFileSystem;


public class TestCon {

    /**

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        POIFSFileSystem fs = null;  
         Document document = new Document(); 

         try {  
             System.out.println("Starting the test");  
             fs = new POIFSFileSystem(new FileInputStream("/document/test2.doc"));  

             HWPFDocument doc = new HWPFDocument(fs);

使用spring的网络服务,我必须从我的帖子请求的主体中获取参数？身体的内容如下: -

source=”mysource”

&json=
{
    "items": [
        {
            "username": "test1",
            "allowed": true
        },
        {
            "username": "test2",
            "allowed": false
        }
    ]
}

网络服务方法如下: -

@RequestMapping(value = "/saveData", headers="Content-Type=application/json", method = RequestMethod.POST)
    @ResponseBody
    public ResponseEntity<Boolean> saveData(@RequestBody String a) throws MyException {
        return new ResponseEntity<Boolean>(uiRequestProcessor.saveData(a),HttpStatus.OK);

    }

请让我知道如何从身体获取参数？我可以把整个身体都放在我的绳子里,但我认为这不是一个有效的方法.请告诉我如何进一步处理.

ContentResolver cr = getContentResolver();
Cursor cur = cr.query(Uri.parse("content://sms/conversations/"), null,null,null, null);     

不工作为什么？
