问题描述
我正在从Android开发者与导航抽屉的例子的应用程序。我做的项目，但我不知道我能打开新的活动从每个项目的招募。
I am making an app from the example of Android Developers with the Navigation Drawer. I made the items but I don't know how I can open new Activity from each of items enlisted.
这是MainActivity：
This is the MainActivity:
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mGalaxyTitles;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
mGalaxyTitles = getResources().getStringArray(R.array.Galaxys_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mGalaxyTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close
) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
selectItem(0);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
switch(item.getItemId()) {
case R.id.action_websearch:
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY, getActionBar().getTitle());
if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
} else {
Toast.makeText(this, R.string.app_not_available, Toast.LENGTH_LONG).show();
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}
}
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch(position) {
case 1:
Intent a = new Intent(MainActivity.this, Page1.class);
startActivity(a);
break;
case 2:
Intent b = new Intent(MainActivity.this, Page2.class);
startActivity(b);
break;
default:
}
}
private void selectItem(int position) {
Fragment fragment = new GalaxyFragment();
Bundle args = new Bundle();
args.putInt(GalaxyFragment.ARG_Galaxy_NUMBER, position);
fragment.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
setTitle(mGalaxyTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
@Override
public void setTitle(CharSequence title) {
mTitle = title;
getActionBar().setTitle(mTitle);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
public static class GalaxyFragment extends Fragment {
public static final String ARG_Galaxy_NUMBER = "Galaxy_number";
public GalaxyFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_Galaxy, container, false);
int i = getArguments().getInt(ARG_Galaxy_NUMBER);
String Galaxy = getResources().getStringArray(R.array.Galaxys_array)[i];
int imageId = getResources().getIdentifier(Galaxy.toLowerCase(Locale.getDefault()),
"drawable", getActivity().getPackageName());
((ImageView) rootView.findViewById(R.id.image)).setImageResource(imageId);
getActivity().setTitle(Galaxy);
return rootView;
}
}
}
和一个抽屉List.xml
And a Drawer List.xml
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:textIsSelectable="false"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:textColor="#fff"
android:background="?android:attr/activatedBackgroundIndicator"
android:minHeight="?android:attr/listPreferredItemHeightSmall"/>
关于这些项目的点击不叫其他人的活动，有什么错？
The click on the items don't call others activities, what is the mistake?
推荐答案
而不是你的code：
private void selectItem(int position) {
Fragment fragment = new GalaxyFragment();
Bundle args = new Bundle();
args.putInt(GalaxyFragment.ARG_Galaxy_NUMBER, position);
fragment.setArguments(args);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
setTitle(mGalaxyTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
使用该code：
private void selectItem(int position) {
switch(position) {
case 1:
Intent a = new Intent(MainActivity.this, Activity1.class);
startActivity(a);
break;
case 2:
Intent b = new Intent(MainActivity.this, Activity2.class);
startActivity(b);
break;
default:
}
}
，然后取出这一部分：（这是没有必要的）
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch(position) {
case 1:
Intent a = new Intent(MainActivity.this, Page1.class);
startActivity(a);
break;
case 2:
Intent b = new Intent(MainActivity.this, Page2.class);
startActivity(b);
break;
default:
}
}
