每次点击我创建的按钮时，我的应用程序都会挂起。我试图将两个Java代码分开，但它们运行良好。有谁可以帮我检查一下？我只想通过onClickListener调用第二个编码。
public class MainActivity extends Activity{
TextView aziangle,elevation,numberof,rightasc,decli,hourangle,solartime;
Button goedit;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initialize();
}
private void initialize() {
// TODO Auto-generated method stub
aziangle=(TextView)findViewById(R.id.tvAziAngle);
elevation=(TextView)findViewById(R.id.tvElevation);
numberof=(TextView)findViewById(R.id.tvNumberof);
rightasc=(TextView)findViewById(R.id.tvRightAsc);
decli=(TextView)findViewById(R.id.tvDecli);
hourangle=(TextView)findViewById(R.id.tvHourAngle);
solartime=(TextView)findViewById(R.id.tvSolarTime);
goedit=(Button)findViewById(R.id.bedit);
goedit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId())
{
case R.id.bedit:
Intent ed=new Intent(MainActivity.this, Menu.class);
startActivity(ed);
break;
}
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
public class Menu extends ListActivity {
String selection[]={"Latitude","Longtitude","TimeZone","DaylightSavingTime","OffsetParameters"};
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, selection));
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
String choosen= selection[position];
try{
Class ourclass = Class.forName("com.example.suntracking" + choosen);
Intent ourintent=new Intent(Menu.this,ourclass);
startActivity(ourintent);
}catch(ClassNotFoundException e) {
e.printStackTrace();
}
}
}

抱歉，我真的不知道如何发布logcat，这些是我在程序的logcat中看到的东西。

我也试过让第二个活动像只有setcontent视图一样简单，但仍然会出现同样的问题。
答案 0 :(得分：0)
菜单已经是android
使用的类名android.view.Menu
尝试将您的第二个活动名称替换为其他名称。 我希望它能解决你的问题。
