我正在看记事本示例在Android SDK在这里看到：http://developer.android.com/resources/samples/NotePad/src/com/example/android/notepad/NoteEditor.html

的是它只能绘制当前行的光标在如http://cdn2.staztic.com/screenshots/simple-notepad-app-al-1.jpg

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

任何建议将是巨大的。的code中的相应和位似乎是在这里：

 保护无效的OnDraw（帆布油画）{

        //获取在查看文本行数。
        诠释计数= getLineCount（）;

        //获取全球矩形和画图对象
        矩形R = mRect;
        涂料粉刷= mPaint;

        / *
         *在绘制矩形一行中的EditText每一行文字
         * /
        的for（int i = 0; I＆LT;计数;我++）{

            //获取文本的当前行的基线坐标
            INT基线= getLineBounds（I，R）;

            / *
             *绘制一条在后台从矩形的左侧到右侧，
             *在一个跌破基线垂直位置，利用画图对象
             *了解详细信息。
             * /
            canvas.drawLine（r.left，基线+1，r.right，基线+1，油漆）;
        }

        //调用父方法来结束
        super.onDraw（画布）;
    }
 

解决方案

这是在code，根据jkhouws1's建议与谷歌的note编辑

 公共类LinedEditText扩展的EditText {
    私人矩形mRect;
    私人油漆mPaint;

    //我们需要这个构造LayoutInflater
    公共LinedEditText（上下文的背景下，ATTRS的AttributeSet）{
        超（背景下，ATTRS）;

        mRect =新的矩形（）;
        mPaint =新的油漆（）;
        mPaint.setStyle（Paint.Style.FILL_AND_STROKE）;
        mPaint.setColor（R.color.edit_note_line）; //这里设置自己的颜色
    }

    @覆盖
    保护无效的OnDraw（帆布油画）{
        //诠释计数= getLineCount（）;

        INT高=的getHeight（）;
        INT line_height = getLineHeight（）;

        诠释计数=身高/ line_height;

        如果（getLineCount（）＆GT;计数）
            数= getLineCount（）; //长文本滚动

        矩形R = mRect;
        涂料粉刷= mPaint;
        INT基准= getLineBounds（0，R）; //第一行

        的for（int i = 0; I＆LT;计数;我++）{

            canvas.drawLine（r.left，基线+1，r.right，基线+1，油漆）;
            基线+ = getLineHeight（）; //下一行
        }

        super.onDraw（画布）;
    }
}
 

在Eclipse IDE中preSS按Ctrl + Shift + O添加所有需要进口

I was taking a look at the notepad sample in the android SDK see here: http://developer.android.com/resources/samples/NotePad/src/com/example/android/notepad/NoteEditor.html

Thing is it only draws the current line the cursor is on e.g http://cdn2.staztic.com/screenshots/simple-notepad-app-al-1.jpg

But I'd like to display lines that fill up the screen e.g. http://www.itismyworld.info/wp-content/uploads/2010/03/AK-notebook.png

Any suggestions would be great. The relevent bit of code seems to be here:

    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 current line of text
            int baseline = getLineBounds(i, r);

            /*
             * Draws a line in the background from the left of the rectangle to the right,
             * at a vertical position one dip below the baseline, using the "paint" object
             * for details.
             */
            canvas.drawLine(r.left, baseline + 1, r.right, baseline + 1, paint);
        }

        // Finishes up by calling the parent method
        super.onDraw(canvas);
    }

This is the code, based on jkhouws1's suggestion and google's note editor

public class LinedEditText extends EditText {
    private Rect mRect;
    private Paint mPaint;

    // we need this constructor for LayoutInflater
    public LinedEditText(Context context, AttributeSet attrs) {
        super(context, attrs);

        mRect = new Rect();
        mPaint = new Paint();
        mPaint.setStyle(Paint.Style.FILL_AND_STROKE);
        mPaint.setColor(R.color.edit_note_line); //SET YOUR OWN COLOR HERE
    }

    @Override
    protected void onDraw(Canvas canvas) {
        //int count = getLineCount();

        int height = getHeight();
        int line_height = getLineHeight();

        int count = height / line_height;

        if (getLineCount() > count)
            count = getLineCount();//for long text with scrolling

        Rect r = mRect;
        Paint paint = mPaint;
        int baseline = getLineBounds(0, r);//first line

        for (int i = 0; i < count; i++) {

            canvas.drawLine(r.left, baseline + 1, r.right, baseline + 1, paint);
            baseline += getLineHeight();//next line
        }

        super.onDraw(canvas);
    }
}
