我需要创建一个android形状,以便只有底部有笔画(虚线).当我尝试以下操作时,笔划将形状从中心平分.有谁知道怎么做对吗？中风需要是底线/边界.我使用形状作为TextView的背景.请不要在意我为什么需要它.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>
        <shape android:shape="rectangle" >
            <solid android:color="#1bd4f6" />
        </shape>
    </item>

    <item>
        <shape android:shape="line" >
            <padding android:bottom="1dp" />

            <stroke
                android:dashGap="10px"
                android:dashWidth="10px"
                android:width="1dp"
                android:color="#ababb2" />
        </shape>
    </item>

</layer-list>

事情是它只绘制光标所在的当前行,例如http://cdn2.staztic.com/screenshots/simple-notepad-app-al-1.jpg

但我想显示填满屏幕的线条,例如http://www.itismyworld.info/wp-content/uploads/2010/03/AK-notebook.png

任何建议都会很棒.相关的代码似乎在这里:

    protected void onDraw(Canvas canvas) {

        // Gets the number of lines of text in the View.
        int count = getLineCount();

        // Gets the global Rect and Paint objects
        Rect r = mRect;
        Paint paint = mPaint;

        /*
         * Draws one line in the rectangle for every line of text in the EditText
         */
        for (int i = 0; i < count; i++) {

            // Gets the baseline coordinates for the …
