如何禁用Android应用中特定按钮的点击声？
这是我的代码:
more1after.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
sc.scrollTo(sc.getScrollX() + 75,
sc.getScrollY() + sc.getWidth() + 5);
}
});
我想绘制一个表,其中最后一列应位于表的最右侧.
这是表行的样子:
Admin (2)New
Network (2)New
这应该是这样的:
Admin (2) New
Network (2) New

我想用 POST 方法调用一个休息网络服务。下面是我需要传递的服务 url 及其参数
Rest Service: https://url/SSOServer/SSO.svc/RestService/Login

public void sendHttpPost() throws ClientProtocolException, IOException{
HttpPost httpPostRequest = new HttpPost(url + buildParams());
// add headers

httpPostRequest.addHeader((String)header.getKey(), (String)header.getValue());
}
HttpClient client = new DefaultHttpClient();
HttpResponse resp;
resp = client.execute(httpPostRequest);
this.respCode = resp.getStatusLine().getStatusCode();
Log.i(TAG, "response code: " + getResponseCode());
this.responsePhrase = resp.getStatusLine().getReasonPhrase();
Log.i(TAG, "error msg: " + getErrorMsg());
HttpEntity entity = resp.getEntity(); …我正在开发一款安卓游戏.
它工作正常,但我有一个问题,如果我从我android manifest的应用程序图标删除下面的行是可见的.如果我不删除这些行,那么我的应用程序图标在我的android上不可见.
<data android:host="mocha" android:path="/RTT/reset"
android:scheme="content" />
这是我的原始Android清单,其中的图标不可见:

更新:使用mDb.execSQL("INSERT INTO " + DATABASE_TABLE + " VALUES (datetime()) ");
我能够插入喜欢date_created=2012-10-10 13:02:08,我希望这种格式10 Oct 2012 12:48如何实现这一点？
我正在研究java中的多线程并创建1个线程,这里是代码:
class SampleThread extends Thread
{
int time;
String name;
boolean autocall;
public SampleThread(int time, String name)
{
this.time = time;
this.name = name;
}
public void run()
{
try{
time = time +1;
updateView(time, name);
//sleep(3000);
}catch(Exception e)
{
e.printStackTrace();
}
//this.stop();
}
}
现在我想每隔3秒运行一次这个线程如何实现这个？
我有java util date Thu Feb 28 15:35:00 GMT+00:00 2013
如何将其转换为HH:MM.
我试图通过下面的代码片段来做到这一点:
SimpleDateFormat formatter = new SimpleDateFormat("HH:MM");
formatter.setTimeZone(TimeZone.getTimeZone("GMT"));
return formatter.format(objDate);
它给出了正确的结果,dd mmm但总是给出02分钟HH:MM
请告诉我这个功能有什么问题？
在我的应用程序中我得到数据库被锁定.
我尝试使用其他帖子中提供的解决方案,但找不到合适的解决方案,这就是我发布此问题的原因.
这是onCreate
DBAdapter db = new DBAdapter(this.getApplicationContext());
dialoge = new Progress_Dialog(this);
dialoge.setCancelable(false);
try {
db.createDataBase();
} catch (IOException e) {
e.printStackTrace();
}
这是create database方法
public void createDataBase() throws IOException{
boolean dbExist = checkDataBase();
if(!dbExist){
this.getReadableDatabase();
try {
copyDataBase();
} catch (IOException e) {
e.printStackTrace();
throw new Error("Error copying database");
}
}
}
以下是checkdatabase方法
private boolean checkDataBase(){
SQLiteDatabase checkDB = null;
try{
String myPath = DB_PATH + DB_NAME;
String myPath2 = DB_PATH + DB_NAME2;
checkDB = SQLiteDatabase.openDatabase(myPath, null,
SQLiteDatabase.OPEN_READWRITE);
if(checkDB …我试图显示一个列表,我使用了一个类Ios.java
public class Ios extends Activity implements OnItemClickListener,OnClickListener
{
list=(ListView) findViewById(R.id.list);
list.setOnItemClickListener(this);
String DATA[] = {"io1","io2","io3","io4","io5"};
IosListAdapter obj = new IosListAdapter(this.getApplicationContext()
,R.layout.row, DATA);
list.setAdapter(obj);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
}}
我的自定义适配器如下:
public IosListAdapter(Context con, int rid,String[] dATA) {
// TODO Auto-generated constructor stub
this.con = con;
this.DATA = dATA;
this.rid = rid;
}
@Override
public …
