<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item
    android:bottom="0dp"
    android:left="-2dp"
    android:right="-2dp"
    android:top="-2dp">
    <shape android:shape="rectangle">
        <stroke
            android:width="1dp"
            android:color="@color/divider" />
    </shape>
</item>

例如，如果您使用recyclerView为您的项目:

在构建。gradle写:

dependencies {
    compile 'com.yqritc:recyclerview-flexibledivider:1.4.0'

如果你想设置颜色，大小和边距值，你可以指定如下:

RecyclerView recyclerView = (RecyclerView) 
findViewById(R.id.recyclerview);
recyclerView.addItemDecoration(
        new HorizontalDividerItemDecoration.Builder(this)
                .color(Color.RED)
                .sizeResId(R.dimen.divider)
                .marginResId(R.dimen.leftmargin, R.dimen.rightmargin)
                .build());

这里是代码“两个文本视图之间的水平分隔线”。 试试这个

    <TextView
        android:id="@id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="5dp"
        android:inputType="textPersonName"
        android:text:"address" />


    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@android:color/black"/>


    <TextView
        android:id="@id/textView7"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textPersonName" 
        android:text:"Upload File" />/>

运行时版本:

View dividerView = new View(getContext());
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
    ViewGroup.LayoutParams.FILL_PARENT, UIUtils.dpToPix(getContext(), 1));
dividerView.setLayoutParams(lp);

TypedArray array = getContext().getTheme()
    .obtainStyledAttributes(new int[] {android.R.attr.listDivider});
Drawable draw = array.getDrawable(0);       
array.recycle();

dividerView.setBackgroundDrawable(draw);
mParentLayout.addView(dividerView);

就这样写:

 android:divider="?android:dividerHorizontal"
 android:showDividers="middle"

完整的例子:

<LinearLayout
        android:id="@+id/llTipInformation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/tvServiceRating"
        android:orientation="horizontal"
        android:divider="?android:dividerHorizontal"
        android:layout_marginTop="@dimen/activity_horizontal_margin"
        android:showDividers="middle">

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center"
            android:text="@string/main.msg.tippercent"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/colorWhite"
            android:layout_marginTop="@dimen/activity_vertical_margin"/>
        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="center"
            android:text="@string/main.msg.tiptotal"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@color/colorWhite"
            android:layout_marginTop="@dimen/activity_vertical_margin"/>

</LinearLayout>

如果你要经常使用它，最好的办法是

styles.xml:

<style name="Seperator">
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">1dp</item>
        <item name="android:background">@color/light_color</item>
    </style>

现在在你的布局中，像这样添加它:

<View style="@style/Seperator" />
