实施侧导航以在活动之间切换

标签： java android android-side-navigation

所以我尝试在我的应用中实现侧面导航，但我似乎找不到按照我想要的方式实现它的方法。我已经看过多个例子，我从korovyansk那里得到的这个非常符合我想要的模具，但是当按下菜单项时，我似乎无法在活动之间切换。我让应用程序通过调整＆＃34; onListItemClick＆＃34;来切换活动。并启动一个新的Intent，但是当活动开始时它会占据整个屏幕并重叠侧边栏动画，从而使它看起来很邋..我希望它在右边的布局中加载活动，而侧面导航正在关闭左边的类似facebook。有没有简单的方法可以做到这一点？

SampleActivity.java 

public class SampleActivity extends FragmentActivity {

@TargetApi(11)
@Override

public void onCreate(Bundle savedInstanceState) {
    int poss;

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

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){
        getActionBar().hide();
    }
    findViewById(R.id.sample_button).setOnClickListener(
            new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int width = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 40, getResources().getDisplayMetrics());
                    SlideoutActivity.prepare(SampleActivity.this, R.id.inner_content, width);
                    startActivity(new Intent(SampleActivity.this,
                            MenuActivity.class));
                    overridePendingTransition(0, 0);
                }
            });
}


}

MenuFragement.java     public class MenuFragment扩展了ListFragment {

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    setListAdapter(new ArrayAdapter<String>(getActivity(),
            android.R.layout.simple_list_item_1, new String[] { " First", " Second", " Third", " Fourth", " Fifth", " Sixth"}));
    getListView().setCacheColorHint(0);
}

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);


     ((MenuActivity)getActivity()).getSlideoutHelper().close();

}


}

XML ..

        android:textSize="19sp"
        android:textColor="#ffffff"

</RelativeLayout>

slideout.xml 

<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent">

<FrameLayout
    android:id="@+id/slideout_placeholder"

    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

</AbsoluteLayout>

编辑： 好的是试图避免这种情况，但现在似乎不可避免。所以即时尝试使用FragmentTransaction。

在onListItemClick下的MenuFragment.java中我有：

     @Override
     public void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);


     ((MenuActivity)getActivity()).getSlideoutHelper().close();
     Fragment dummy = new Dummy();
     FragmentTransaction transaction = getFragmentManager().beginTransaction();

     // Replace whatever is in the fragment_container view with this fragment,
     // and add the transaction to the back stack
     transaction.replace(R.id.inner_content, dummy);
     transaction.addToBackStack(null);

     // Commit the transaction
     transaction.commit();
}

Dummy.java 

public class Dummy extends Fragment{
 View blag;
 @TargetApi(11)

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

}
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                      Bundle savedInstanceState) {

   blag = inflater.inflate(R.layout.samplex, container, false);
  //(samplex is same as sample.xml just different logo
  return blag;
}



}

但它现在崩溃并显示错误消息：03-22 11：54：24.469：E / AndroidRuntime（31673）：java.lang.IllegalArgumentException：找不到ID为0x7f060000的视图，用于片段虚拟{42540328＃ 1 id = 0x7f060000} 任何关于为什么会这样的想法。

1 个答案:

答案 0 :(得分：1)

这是一个简单的答案：

不要使用活动！

只有一个活动的布局包含R.id.menu（菜单）和R.id.content（示例名称），然后您将使用Fragment和FragmentTransaction以及FragmentManager来操作R内的片段.id.content（虽然菜单会有很好的动画效果）。

此外，我建议您使用此库作为菜单：https://github.com/jfeinstein10/SlidingMenu我以前使用它并且它非常好用。

快乐的编码。
