问题描述
我想让我的应用程序的工作只能在横向模式,但不能使它发挥作用。我已经给 screenOrientation =景观
即使第一页将在风景模式和其他活动将会在肖像。
XML文件
<应用机器人:图标=@可绘制/图标机器人:标签=@字符串/ APP_NAME>

JAVA CLASS
公共类ObjectivesPage延伸活动{
的ImageButton imgButton;
公共无效的onCreate(包savedInstanceState){
super.onCreate(savedInstanceState);
的setContentView(R.layout.objectivespage);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
imgButton =(的ImageButton)findViewById(R.id.buttonCloseNGo);
imgButton.setOnClickListener(onClickCloseNGo);
}
私人OnClickListener onClickCloseNGo =新OnClickListener(){
公共无效的onClick(视图v){
意向意图=新的意图(ObjectivesPage.this,MenuPage.class);
startActivity(意向);
}
};
}
请这部分的表现,因为它已经是了。例如,考虑IntroHome活动。
<活动机器人:名称=。IntroHome
机器人:标签=@字符串/ APP_NAME
机器人:screenOrientation =风景
>
< /活性GT;
和对活动的XML,请确保您有IntroHome活动布局XML的仅在布局土地文件夹。通过这种方式,活动/活动,你将只能说明你已经定义了XML的景观版本。
I want to make my app work only in landscape mode but can't make it work. I have given screenOrientation = "landscape"
even though the first page will be in landscape mode and other activity will be in portrait.
XML FILE
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Main"
android:label="@string/app_name"
android:screenOrientation="landscape" android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".IntroHome"
android:label="@string/app_name"
android:screenOrientation="landscape">
</activity>
<activity android:name=".ObjectivesPage"
android:label="@string/app_name"
android:screenOrientation="landscape" >
</activity>
<activity android:name=".MenuPage"
android:label="@string/app_name"
android:screenOrientation="landscape" >
</activity>
</application>
JAVA CLASS
public class ObjectivesPage extends Activity{
ImageButton imgButton;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.objectivespage);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
imgButton = (ImageButton)findViewById(R.id.buttonCloseNGo);
imgButton.setOnClickListener(onClickCloseNGo);
}
private OnClickListener onClickCloseNGo = new OnClickListener(){
public void onClick(View v) {
Intent intent = new Intent(ObjectivesPage.this,MenuPage.class);
startActivity(intent);
}
};
}
Keep this part of the manifest as it already is. For example, consider the IntroHome activity.
<activity android:name=".IntroHome"
android:label="@string/app_name"
android:screenOrientation="landscape"
>
</activity>
And for the activity XML, make sure you have the IntroHome activity layout XML only in the layout-land folder. This way, the activity / activities you have will only show the the landscape version of the XML that you have defined.
