我怎样才能改变纵向和横向当UI [英] How can i change the UI when in portrait and landscape
本文介绍了我怎样才能改变纵向和横向当UI的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
据我了解这里已经有问题，使用方向和横向的布局，这只是我想要做的是有点不同。我的目标，当旋转为横向完全更改UI例如人像时，它显示常规信息，但旋转时，显示的表。
这会涉及到有两个独立的活动，并使用if语句根据方向开始活动？我一直在使用一个简单的横向布局尝试，但是当我改变方向它关闭对所有findviewbyids在纵向布局使用的物品一个NullPointerException异常。

希望它帮助。
I understand there are already questions here on using orientation and landscape layouts however what I want to do is a bit different. I am aiming to change the UI entirely when rotated to landscape e.g when portrait it displays regular information but when rotated shows a table.
Would this involve having two separate activities and using an if statement to start the activity depending on orientation? I have tried using a simple landscape layout but when I change the orientation it closes on a nullpointerexception for all the findviewbyids for items used in the portrait layout.
Added code for manusunny
public class PortraitFragment extends FragmentActivity {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.content_main, container, false);
ImageView imageView = (ImageView) view.findViewById(R.id.imageView);
TextView lessonString = (TextView) view.findViewById(R.id.primaryText);
TextView subTextString = (TextView) view.findViewById(R.id.secondaryText);
return view;
}
}
public class LandscapeFragment extends FragmentActivity {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.content_portrait, container, false);
ImageView imageView = (ImageView) view.findViewById(R.id.imageView);
TextView lessonString = (TextView) view.findViewById(R.id.primaryText);
TextView subTextString = (TextView) view.findViewById(R.id.secondaryText);
return view;
}
}

解决方案
Use a single activity and two fragments. Look at this example,
MainActivity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
res/layout/activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.manusunny.myapplication.MainActivity"
android:orientation="vertical">
<fragment android:name="com.manusunny.myapplication.PortraitFragment"
android:id="@+id/portrait_fragment"
android:layout_width="match_parent"
android:layout_height="30dp" />
</LinearLayout>
res/layout-land/activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.manusunny.myapplication.MainActivity"
android:orientation="vertical">
<fragment android:name="com.manusunny.myapplication.LandscapeFragment"
android:id="@+id/landscape_fragment"
android:layout_width="match_parent"
android:layout_height="30dp" />
</LinearLayout>
PortraitFragment.java
public class PortraitFragment extends Fragment {
public PortraitFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_portrait, container, false);
// do something
return view
}
}
res/layout/fragment_portrait.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.manusunny.myapplication.PortraitFragment">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Portrait" />
</FrameLayout>
LandscapeFragment.java
public class LandscapeFragment extends Fragment {
public LandscapeFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_landscape, container, false);
// do something
return view
}
}
res/layout/fragment_landscape.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.manusunny.myapplication.LandscapeFragment">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Landscape" />
</FrameLayout>
This will show 'Portrait' in portrait screen and 'Landscape' in landscape screen.
Hope it helps.
