我为我的maiActivity编写了这个XML代码:

    <RelativeLayout 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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <ImageView
        android:id="@+id/backImage"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:adjustViewBounds="true"
        android:src="@drawable/back" />

</RelativeLayout>



我希望当表单开始我的活动创建全屏和图像背景填充或适合活动。

如果您想将图片作为背景,则不需要使用Imageview。

使用android:background =&#34; @ drawable / back&#34;在相对布局声明中;)

一个选项是将布局更改为FrameLayout并将这些属性添加到ImageView:

android:src="@drawable/your_image"
android:scaleType = "centerCrop"

试试这个:

布局

<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"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:fitsSystemWindows="true"
    android:background="#ffffff"
    tools:context="com.smbds.app.activities.SplashScreenActivity">

    <ImageView
        android:src="@drawable/ic_branding_splashscreen"
        android:layout_centerInParent="true"
        android:keepScreenOn="true"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

活动

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.activity_splash_screen);

    resources = getResources();

你可以这样做:

1-实际上

public class YoutActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main);
    }
}

2- XML: 您可以在AndroidManifest.xml

中进行设置
<activity android:name=".YoutActivity "
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>

当你设置绑定

时,也会让图像充满屏幕
