当我点击我的列表视图，我希望它带我到另一个活动，当我点击第二个位置，我希望它带我去一个不同的activity..etc第一的位置。我试图写code，当我点击我的名单上的第一项查看需要我的活动MrsClubb但每当我点击的项目它出现消息不幸应用程序名有停止工作，然后在应用程序关闭。

When I click on the first position of my list view I want it to take me to another activity, and when I click on the second position I want it to take me to a different activity..etc. I have tried to write code that when I click on the first item of my list view it takes me to the activity "MrsClubb" but whenever I click on the item it comes up with the message "unfortunately "app name" has stopped working" and then the app closes.

任何想法？

下面是code我的应用程序的各个位：

Here is the code for various bits of my app:

MainActivity.java

MainActivity.java

public class MainActivity extends ActionBarActivity {

DrawerLayout mDrawerLayout;
ListView mDrawerList;
ActionBarDrawerToggle mDrawerToggle;
String[] mDrawerListItems;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
    mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer);
    mDrawerList = (ListView)findViewById(android.R.id.list);
    mDrawerListItems = getResources().getStringArray(R.array.drawer_list);
    mDrawerList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mDrawerListItems));
    mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            switch(position) {
                case 0:
                    Intent i = new Intent(MainActivity.this, MrsClubb.class);
                    startActivity(i);
            }
            mDrawerLayout.closeDrawer(mDrawerList);

        }
    });
    mDrawerToggle = new ActionBarDrawerToggle(this,
            mDrawerLayout,
            toolbar,
            R.string.drawer_open,
            R.string.drawer_close){
        public void onDrawerClosed(View v){
            super.onDrawerClosed(v);
            invalidateOptionsMenu();
            syncState();
        }
        public void onDrawerOpened(View v){
            super.onDrawerOpened(v);
            invalidateOptionsMenu();
            syncState();
        }
    };
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
    mDrawerToggle.syncState();
}

@Override
protected void onPostCreate(Bundle savedInstanceState){
    super.onPostCreate(savedInstanceState);
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig){
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);
}

@Override
public boolean onOptionsItemSelected(MenuItem item){
    switch (item.getItemId()){
        case android.R.id.home: {
            if (mDrawerLayout.isDrawerOpen(mDrawerList)){
                mDrawerLayout.closeDrawer(mDrawerList);
            } else {
                mDrawerLayout.openDrawer(mDrawerList);
            }
            return true;
        }
        default: return super.onOptionsItemSelected(item);
    }
}
}

清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.jonatboard.jonat.htssoundboard" >

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".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>

</application>

</manifest>

活动我想要的项目要带我去的时候是点击现在还是空的，只有有这个code。在它：

The activity I want the item to take me to when it is click is currently empty and only has this code in it:

public class MrsClubb {
}

如果您需要查看更多code来帮助你，那么请让我知道。

If you need to see any more code to help you then please let me know.

推荐答案

定义 MrsClubb 类

public class MrsClubb extends Activity{

    @Override
    public void onCreate(Bundle savedInstanceState){

        setContentView(R.id.mrsClubbLayout);
        ....
        ....

    }

}

和覆盖活动类的的onCreate（）办法（至少是）。另外补充申报的清单：

and override the onCreate() method of the Activity class (at the very least). Also add the declaration in the manifest:

<activity
    android:name=".MrsClubb"
    android:label="@string/mrs_clubb_activity_title" >
</activity>
