小编vim*_*hra的帖子

有人可以帮我解决这个问题.我希望我的活动全屏,并希望从屏幕上删除标题.我尝试了几种方法,但无法将其删除.

活动代码:

public class welcomepage extends Activity {
    private Button btn;
    EditText userName,passWord;
    DatabaseHandler dbHandler;
    Context ctx =this;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //Remove title bar
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_welcomepage);
   }
}

和Activity.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:background="@drawable/pic1"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.edkul.vimal.edkul.welcomepage">

</RelativeLayout>

我想删除以蓝色显示的标题栏.请找到参考图像:

AndroidManifest.xml中

<application
        android:minSdkVersion="3"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/Theme.AppCompat.NoActionBar">
        <activity
            android:name=".welcomepage"
            android:label="@string/app_name"
            android:theme="@style/Theme.AppCompat.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category    android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
</application>

我正在尝试克隆位存储桶回购。在安装 git 后执行以下命令后，我面临以下问题：

$ git clone https://usernam@bitbucket.org/username/reponame.git
Error :fatal: unable to access'https://username@bitbucket.org/username/reponame.git/': 
Failed to connect to hostname port 8000: Connection refused

我怎样才能克服这个错误信息？

我正在尝试从外部源向Slack通道发送通知。我正在尝试将URL链接放在附件的字段标记内。有没有办法做到这一点？
