应用程序挂在按钮的onClickListener

Question

每次单击我创建的按钮时，我的应用程序都会挂起。我尝试将这两个Java代码分开，它们工作得很好。谁能帮我查一下吗？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();
    }
}
}


<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.suntracking"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.suntracking.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.example.suntracking.Menu"
            android:label="@string/app_name" >

        </activity>
    </application>

</manifest>

编辑：我再次检查，我很确定问题出在OnClickListener中，因为当我删除这些内容时，我可以按下按钮，它不会挂起，尽管它也不会转到其他页面。

我还尝试将第二个活动简化为仅显示setcontent视图，但仍然出现了相同的问题。

Answer 1

菜单已经是android使用的类名

android.view.Menu

尝试将第二个活动名称替换为其他。我希望它能解决你的问题。
