我刚安装了SDK
和ADT Eclipse plugin
。我试图做的是一个简单的“Hello,World”程序。我正在使用2.2 (8) API
。这里是我的代码:Android Hello World应用程序无法正常工作,模拟器上没有文字显示
package com.example.hello;
import android.app.Activity;
import android.widget.TextView;
import android.os.Bundle;
public class HelloWorld extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView txt = new TextView(this);
txt.setText("Hello, Android");
setContentView(txt);
}
}
我Eclipse
控制台:
[2010-09-02 13:27:32 - HelloWorld] ------------------------------
[2010-09-02 13:27:32 - HelloWorld] Android Launch!

而且在我的模拟器(5554:安卓)没有显示只是一个空白屏幕,酷fonted “Android” 的印记。我基本上失踪了什么?
