앱의 배경 이미지를 반복하는 방법

앱에서 배경 이미지를 설정했지만 배경 이미지가 작고 반복하여 전체 화면을 채우고 싶습니다. 어떻게해야합니까?

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/bg"
    android:tileMode="repeat">

좋아, 여기 내 앱에있는 것이 있습니다. ListView스크롤하는 동안 s가 검게 변하는 것을 막기위한 핵을 포함합니다 .

drawable / app_background.xml :

<?xml version="1.0" encoding="utf-8"?>
    <bitmap xmlns:android="http://schemas.android.com/apk/res/android"
        android:src="@drawable/actual_pattern_image"
        android:tileMode="repeat" />

values ​​/ styles.xml :

<?xml version="1.0" encoding="utf-8"?>
<resources>

  <style name="app_theme" parent="android:Theme">
    <item name="android:windowBackground">@drawable/app_background</item>
    <item name="android:listViewStyle">@style/TransparentListView</item>
    <item name="android:expandableListViewStyle">@style/TransparentExpandableListView</item>
  </style>

  <style name="TransparentListView" parent="@android:style/Widget.ListView">
    <item name="android:cacheColorHint">@android:color/transparent</item>
  </style>

  <style name="TransparentExpandableListView" parent="@android:style/Widget.ExpandableListView">
    <item name="android:cacheColorHint">@android:color/transparent</item>
  </style>

</resources>

AndroidManifest.xml :

//
<application android:theme="@style/app_theme">
//

drawable xml에는 속성이 있습니다. android : tileMode = "반복"

다음은 백그라운드 이미지 반복의 순수 Java 구현입니다.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.bg_image);
    BitmapDrawable bitmapDrawable = new BitmapDrawable(bmp);
    bitmapDrawable.setTileModeXY(Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);
    LinearLayout layout = new LinearLayout(this);
    layout.setBackgroundDrawable(bitmapDrawable);
}

이 경우 배경 이미지는 res / drawable / bg_image.png에 저장해야합니다.

plowman의 답변을 확장하여 Java로 배경 이미지를 변경하는 데 사용되지 않는 버전이 있습니다.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Bitmap bmp = BitmapFactory.decodeResource(getResources(),
            R.drawable.texture);
    BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(),bmp);
    bitmapDrawable.setTileModeXY(Shader.TileMode.REPEAT,
            Shader.TileMode.REPEAT);
    setBackground(bitmapDrawable);
}
