我是一名初学者，正在尝试使用 developer.android.com 运行 Hello world 应用程序。我正在使用 eclipse helios、Android 2.3、最新的 jdk 和 sdk。使用window xp，所以有32位版本。我无法在弹出的模拟器窗口上获得输出。窗格或主屏幕上没有输出。我正在使用默认的 ddms.bat 并且没有进行任何更改。任何人都可以建议做什么。

附上我的 ddms.bat 和 java 代码

ddms.bat

setlocal

rem Set up prog to be the path of this script, including following symlinks,
rem and set up progdir to be the fully-qualified pathname of its directory.
set prog=%~f0

rem Change current directory and drive to where the script is, to avoid
rem issues with directories containing whitespaces.
cd /d %~dp0

rem Check we have a valid Java.exe in the path.
set java_exe=
call lib\find_java.bat
if not defined java_exe goto :EOF

set jarfile=ddms.jar
set frameworkdir=

if exist %frameworkdir%%jarfile% goto JarFileOk
    set frameworkdir=lib\

if exist %frameworkdir%%jarfile% goto JarFileOk
    set frameworkdir=..\framework\

:JarFileOk

if debug NEQ "%1" goto NoDebug
    set java_debug=-agentlib:jdwp=transport=dt_socket,server=y,address=8050,suspend=y
    shift 1
:NoDebug

set jarpath=%frameworkdir%%jarfile%

if not defined ANDROID_SWT goto QueryArch
    set swt_path=%ANDROID_SWT%
    goto SwtDone

:QueryArch

    for /f %%a in ('%java_exe% -jar %frameworkdir%archquery.jar') do set swt_path=%frameworkdir%%%a

:SwtDone

if exist %swt_path% goto SetPath
    echo SWT folder '%swt_path%' does not exist.
    echo Please set ANDROID_SWT to point to the folder containing swt.jar for your platform.
    exit /B

:SetPath
set javaextdirs=%swt_path%;%frameworkdir%

call %java_exe% %java_debug% -Dcom.android.ddms.bindir= -classpath "%jarpath%;%swt_path%\swt.jar" com.android.ddms.Main %*

Java 代码

package com.example.helloandroid;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TextView tv = new TextView(this); 
        tv.setText("Hello, Android"); 
        setContentView(tv);
        }
}

我遇到了这个“问题”，模拟器需要很长时间才能启动。静置 10 分钟，文字就会出现！
