Question

我正在尝试使用Canvas drawVertices方法绘制quadriliteral。它每次都会崩溃：

private final float[] verts = new float[] {
        0, 0,                   // 0 Top left
        0, 800f,                // 1 Bottom left
        480f, 800f,             // 2 Bottom right
        480f,0f                 // 3 Top right
    };
/* Order to draw the vertices */
private short[] indices = { 0, 1, 2, 0, 2, 3 };
private final int[] colors = new int[] {
        Color.parseColor("#75AADB"),
        Color.parseColor("#75AADB"),
        Color.parseColor("#75AADB"),
        Color.parseColor("#75AADB"),
        Color.parseColor("#75AADB"),
        Color.parseColor("#75AADB")
};

最后我称之为实际绘制方法：

paint.setStyle（Style.FILL）; paint.setColor（Color.RED）;

canvas.drawVertices(Canvas.VertexMode.TRIANGLES, verts.length, verts, 0, null, 0, colors, 0, indices, 0, indices.length, paint);

Answer 1

很晚，但尝试在您的colors数组中添加两个Color.parseColor("#75AADB")。 verts.length必须等于colors.length

android Canvas.drawVertices也没有异常崩溃
