Eclipse android 主菜单，带有启动新按钮的按钮 activity(ies)
eclipse android main menu with button to start new activity(ies)
我想要一个带有按钮的主菜单，当 clicked.Please 更正我编写的代码时，每个按钮都会转到自己的选项卡，如下所示：
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.mainmenu);
}
public void produkdanpromobutton(View view){
Intent Intentprodukpromo = new Intent(this , Produkpromotest.class);
startActivity(Intentprodukpromo);
}
public void simulasilist(View view){
Intent Intentsimulasilist = new Intent(this , Simulasilistcode.class);
startActivity(Intentsimulasilist);
}
public void aboutus(View view){
Intent Intentaboutus = new Intent(this , Aboutuscode.class);
startActivity(Intentaboutus);
}}
我已经在清单和 xml 布局中添加了活动，但是
它不起作用，当我在 eclipse 模拟器（android 5554 模拟器）上尝试它时，当我单击这些按钮之一时，应用程序将崩溃。
Produkpromotest.java
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.productpromotab);
}
Simulatorlistcode.java
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.mainmenu);
}
Simulasilistcode.java 发现布局错误：
正确的：
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.simulasilisttab);
}
Aboutuscode.java
@Override
