我正在嘗試使用具有一些活動且沒有片段的導航抽屜。我讀我通過幾個答案在這裏和this結束了和我心中已經得到了相同的問題,因爲用戶Dediqated,這裏是我的代碼:具有多個活動的Android導航抽屜
BaseActivity.java:

public class BaseActivity extends Activity {
public DrawerLayout drawerLayout;
public ListView drawerList;
public String[] layers;
private ActionBarDrawerToggle drawerToggle;
protected void onCreate(Bundle savedInstanceState) {
try {
// R.id.drawer_layout should be in every activity with exactly the same
// id.
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerToggle = new ActionBarDrawerToggle((Activity) this, drawerLayout,
R.drawable.ic_drawer, 0, 0) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(R.string.hello_world);
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(R.string.hello_world);
}
};
drawerLayout.setDrawerListener(drawerToggle);
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
layers = getResources().getStringArray(R.array.planets_array);
drawerList = (ListView) findViewById(R.id.left_drawer);
drawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, android.R.id.text1, layers));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
e.printStackTrace();
e.printStackTrace();
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (drawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
drawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
drawerToggle.onConfigurationChanged(newConfig);
}
}
TestActivity.java:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);

<TextView xmlns:android="http://schemas.android.com/apk/res/android"

在BaseActivity.java符合drawerLayout.setDrawerListener(drawerToggle);
Eclipse中拋出一個NullPointerException,我只是不知道爲什麼。
對於同樣的問題,我已經提出了一個額外的問題,但我是新的,不允許添加評論。
你是完全正確的,這工作得很好。在這一點上,我只需要知道我可以在哪裏定義哪個activity在哪個listView-Element應該啓動 – user3488420
好吧,你必須考慮一些邏輯來執行點擊並註冊一個'OnClickListener',因爲[在這裏](http: //developer.android.com/training/implementing-navigation/nav-drawer.html#Init)。最簡單的方法是創建一個靜態數組並使用索引。 – MalaKa
您在基本活動中有抽屜佈局,並且正在設置其他活動的佈局。基本活動如何在此場景中獲取抽屜佈局視圖 –
