我刚刚安装了SDK
和ADT Eclipse plugin
。我想做的是一个简单的“Hello, World”程序。我正在使用2.2 (8) API
. 这是我的代码:
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);
}
}
我的Eclipse
控制台:
[2010-09-02 13:27:32 - HelloWorld] ------------------------------

在我的模拟器 (5554:Android) 上,除了一个带有酷字体“Android”印记的空白屏幕外,什么也没有显示。我从根本上缺少什么?
