小编shr*_*pal的帖子

我想让我的应用程序仅在横向模式下工作,但无法使其工作.我已经给出了screenOrientation = "landscape"即使第一页将处于横向模式,其他活动将是纵向的.

XML文件

<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); …

我们如何在Android中关闭自动亮度？

我们如何解决这类错误 - >"这个应用程序,或它使用的库,正在使用NSQuickDrawView,已被弃用.应用程序应停止使用QuickDraw并转移到Quartz."

在MainActivity.java中

DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://192.168.5.10/ijoomer_development/index.php?option=com_ijoomer&plg_name=jomsocial&pview=user&ptask=login&tmpl=component");
StringBuffer strBuffer = new StringBuffer("<data><username>" + username + "</username><password>" + password + "</password><lat>" + lat +"</lat><long>"+ longi +"</long></data>");
StringEntity strEntity = new StringEntity(strBuffer.toString());
post.setEntity(strEntity);
HttpResponse response = client.execute(post);

InputStream in = response.getEntity().getContent();

MainActivity mActivity = new MainActivity();
System.out.println(mActivity.convertStreamToString(in));

demoHandler = new DemoHandler();
ArrayList<UserBean> users = demoHandler.parse(in);
Log.i("VALUE OF USER",""+users);

在DemoHandler.java中

public ArrayList<UserBean> parse(InputStream in) {
    try {
        SAXParser parser = SAXParserFactory.newInstance().newSAXParser();
        parser.parse(in, this);

    } catch (ParserConfigurationException e) {
        // …

private int pos = position;
                    @Override
                    public void onClick(View v) {
                        Toast.makeText(context, "Click-" + String.valueOf(pos), Toast.LENGTH_SHORT).show(); 
                        iBean = (InboxBean)result.get(position);
                        ConstantData.inbox_subject = iBean.subject;
                        ConstantData.inbox_body = iBean.body;
                        ConstantData.inbox_postDate = iBean.postdate;

                        startActivity(new Intent(InboxActivity.this,InboxDetailActivity.class));//getting error at startActivity 
                    }
            });

我在startActivity行遇到以下错误: "Cannot make a static reference to the non-static method startActivity(Intent) from the type Activity"

请帮忙.

如何将ttf文件用于按钮的文本？

我想编辑存储在SD卡上的.txt文件.在我的应用程序中,我必须编写用户活动数据.

因此,每当用户打开应用程序并执行某些操作时,都应使用新数据更新.txt文件.
