Gridview制作表格

最简单的方法

1.在GridView里设置一些属性

android:background="#000000" 背景色黑色

android:horizontalSpacing="1sp" 水平间距1sp

android:verticalSpacing="1sp" 垂直间距1sp

android:padding="1sp" 与里面的内容间隔1sp

2.在GridView的Adapter的布局里设置一些属性

android:background="#ffffff“

这样就实现表格的布局样式了

import hy.mingancai.tongqutang.R; import android.content.Context; import android.graphics.Canvas; import android.graphics.Paint; import android.util.AttributeSet; import android.view.View; import android.widget.GridView; public class LineGridView extends GridView { public LineGridView(Context context) { super(context); // TODO Auto-generated constructor stub } public LineGridView(Context context, AttributeSet attrs) { super(context, attrs); } public LineGridView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override protected void dispatchDraw(Canvas canvas) { super.dispatchDraw(canvas); // 第一个视图 View localView1 = getChildAt(0); // 列数 int column = getWidth() / localView1.getWidth(); // 孩子数 int childCount = getChildCount(); Paint localPaint; localPaint = new Paint(); localPaint.setStyle(Paint.Style.STROKE); localPaint.setColor(getContext().getResources().getColor(R.color.main)); for (int i = 0; i < childCount; i++) { View cellView = getChildAt(i); if ((i + 1) % column == 0) { canvas.drawLine(cellView.getLeft(), cellView.getBottom(), cellView.getRight(), cellView.getBottom(), localPaint); } else if ((i + 1) > (childCount - (childCount % column))) { canvas.drawLine(cellView.getRight(), cellView.getTop(), cellView.getRight(), cellView.getBottom(), localPaint); } else { canvas.drawLine(cellView.getRight(), cellView.getTop(), cellView.getRight(), cellView.getBottom(), localPaint); canvas.drawLine(cellView.getLeft(), cellView.getBottom(), cellView.getRight(), cellView.getBottom(), localPaint); } } if (childCount % column != 0) { for (int j = 0; j < (column - childCount % column); j++) { View lastView = getChildAt(childCount - 1); canvas.drawLine(lastView.getRight() + lastView.getWidth() * j, lastView.getTop(), lastView.getRight() + lastView.getWidth() * j, lastView.getBottom(), localPaint); } } } }

这样也可以，不过这个实现的效果是表格的最外层没线条
